GENERAL DESCRIPTION
The ADR01, ADR02, ADR03, and ADR06 are precision 10 V, 5 V, 2.5 V, and 3.0 V band gap voltage references featuring high accuracy, high stability, and low power. The parts are housed in tiny SC70-5 and TSOT-5 packages, as well as the SOIC-8 versions. The SOIC-8 versions of the ADR01, ADR02, and ADR03 are drop-in replacements1 to the industry-standard REF01, REF02, and REF03. The small footprint and wide operating range make the ADR0x references ideally suited for general-purpose and space-constraint applications. With an external buffer and a simple resistor network, the TEMP terminal can be used for temperature sensing and approximation. A TRIM terminal is provided on the devices for fine adjustment of the output voltage. The ADR01, ADR02, ADR03, and ADR06 are compact, low drift voltage references that provide an extremely stable output voltage from a wide supply voltage range. They are available in SC70-5, TSOT-5, and SOIC-8 packages with A and B grade selections. All parts are specified over the extended industrial (-40C to +125C) temperature range.

JA is specified for the worst-case conditions, that is, JA is specified for devices soldered in circuit boards for surface-mount packages.
Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although these products feature proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

ADR01/ADR02/ADR03/ADR06
PARAMETER DEFINITIONS
Temperature Coefficient
The change of output voltage with respect to operating temperature changes normalized by the output voltage at 25C. This parameter is expressed in ppm/C and can be determined by the following equation:
TCVO [ ppm / C ] = VO (T2 ) - VO (T1 ) x 10 6 VO ( 25C ) x T2 - T1
Thermal Hysteresis
Defined as the change of output voltage after the device is cycled through temperature from +25C to -40C to +125C and back to +25C. This is a typical value from a sample of parts put through such a cycle.
VO _ HYS = VO ( 25C ) - VO _ TC
where: VO(25C) = VO at 25C VO(T1) = VO at Temperature 1 VO(T2) = VO at Temperature 2
VO _ HYS [ ppm ] =
VO ( 25C ) - VO _ TC VO ( 25C )
x 10 6
Line Regulation
The change in output voltage due to a specified change in input voltage. This parameter accounts for the effects of self-heating. Line regulation is expressed in either percent per volt, partsper-million per volt, or microvolts per volt change in input voltage.
where: VO(25C) = VO at 25C VO_TC = VO at 25C after temperature cycle at +25C to -40C to +125C and back to +25C
NOTES
Input Capacitor
Input capacitors are not required on the ADR01/ADR02/ ADR03/ADR06. There is no limit for the value of the capacitor used on the input, but a 1 F to 10 F capacitor on the input improves transient response in applications where the supply suddenly changes. An additional 0.1 F in parallel also helps to reduce noise from the supply.
Load Regulation
The change in output voltage due to a specified change in load current. This parameter accounts for the effects of self-heating. Load regulation is expressed in either microvolts per milliampere, parts-per-million per milliampere, or ohms of dc output resistance.
Output Capacitor
The ADR01/ADR02/ADR03/ADR06 do not require output capacitors for stability under any load condition. An output capacitor, typically 0.1 F, filters out any low level noise voltage and does not affect the operation of the part. On the other hand, the load transient response can be improved with an additional 1 F to 10 F output capacitor in parallel. A capacitor here acts as a source of stored energy for a sudden increase in load current. The only parameter that degrades by adding an output capacitor is the turn-on time, and it depends on the size of the capacitor chosen.
Long-Term Stability
Typical shift of output voltage at 25C on a sample of parts subjected to a test of 1,000 hours at 25C:
VO = VO (t0 ) - VO (t1 )
VO [ ppm] = VO (t0 ) - VO (t1 ) x 10 6 VO (t0 )
where: VO(t0) = VO at 25C at Time 0 VO(t1) = VO at 25C after 100 hours of operation at 25C The majority of the shift is seen in the first 200 hours, and, as time goes by, the drift decreases significantly. So for the subsequent 1,000 hours' time points, this drift is much smaller than the first.

ADR01/ADR02/ADR03/ADR06
APPLICATIONS
The ADR01/ADR02/ADR03/ADR06 are high precision, low drift 10 V, 5 V, 2.5 V, and 3.0 V voltage references available in an ultracompact footprint. The SOIC-8 version of the devices is a drop-in replacement of the REF01/REF02/ REF03 sockets with improved cost and performance. These devices are standard band gap references. The band gap cell contains two NPN transistors (Q18 and Q19) that differ in emitter area by 2x. The difference in their VBE produces a proportional-to-absolute temperature current (PTAT) in R14, and, when combined with the VBE of Q19, produces a band gap voltage, VBG, that is almost constant in temperature. With an internal op amp and the feedback network of R5 and R6, VO is set precisely at 10 V, 5 V, 2.5 V, and 3.0 V for the ADR01, ADR02, ADR06, and ADR03, respectively. Precision laser trimming of the resistors and other proprietary circuit techniques are used to further enhance the initial accuracy, temperature curvature, and drift performance of the ADR01/ADR02/ADR03/ADR06.

Output Adjustment
The ADR01/ADR02/ADR03/ADR06 trim terminal can be used to adjust the output voltage over a nominal voltage. This feature allows a system designer to trim system errors by setting the reference to a voltage other than 10 V/5 V/2.5 V/3.0 V. For finer adjustment, a series resistor of 470 k can be added. With the configuration shown in Figure 36, the ADR01 can be adjusted from 9.70 V to 10.05 V, the ADR02 can be adjusted from 4.95 V to 5.02 V, the ADR06 can be adjusted from 2.8 V to 3.3 V, and the ADR03 can be adjusted from 2.3 V to 2.8 V. Adjustment of the output does not significantly affect the temperature performance of the device, provided the temperature coefficients of the resistors are relatively low.

Temperature Monitoring
As described previously, the ADR01/ADR02/ADR03/ADR06 provide a TEMP output (Pin 3) that varies linearly with temperature. This output can be used to monitor the temperature change in the system. The voltage at VTEMP is approximately 550 mV at 25C, and the temperature coefficient is approximately 1.96 mV/C (see Figure 37). A voltage change of 39.2 mV at the TEMP pin corresponds to a 20C change in temperature.
Figure 34. Simplified Schematic Diagram
The PTAT voltage is made available at the TEMP pin of the ADR01/ADR02/ADR03/ADR06. It has a stable 1.96 mV/C temperature coefficient, such that users can estimate the temperature change of the device by knowing the voltage change at the TEMP pin.
APPLYING THE ADR01/ADR02/ADR03/ADR06
The devices can be used without any external components to achieve the specified performance. Because of the internal op amp amplifying the band gap cell to 10 V/5 V/2.5 V/3.0 V, power supply decoupling helps the transient response of the ADR01/ADR02/ADR03/ADR06. As a result, a 0.1 F ceramic type decoupling capacitor should be applied as close as possible

LOW COST CURRENT SOURCE
Unlike most references, the ADR01/ADR02/ADR03/ADR06 employ an NPN Darlington in which the quiescent current remains constant with respect to the load current, as shown in Figure 24. As a result, a current source can be configured as shown in Figure 40 where ISET = (VOUT - VL)/RSET. IL is simply the sum of ISET and IQ. Although simple, IQ varies typically from 0.55 to 0.65 mA, limiting this circuit to general-purpose applications.

Figure 37. Voltage at TEMP Pin vs. Temperature
The TEMP function is provided as a convenience rather than a precise feature. Because the voltage at the TEMP node is acquired from the band gap core, current pulling from this pin has a significant effect on VOUT. Care must be taken to buffer the TEMP output with a suitable low bias current op amp, such as the AD8601, AD820, or OP1177, all of which would result in less than a 100 V change in VOUT (see Figure 38). Without buffering, even tens of microamps drawn from the TEMP pin can cause VOUT to fall out of specification.

PRECISION CURRENT SOURCE WITH ADJUSTABLE OUTPUT
A precision current source, on the other hand, can be implemented with the circuit shown in Figure 41. By adding a mechanical or digital potentiometer, this circuit becomes an adjustable current source. If a digital potentiometer is used, the load current is simply the voltage across terminals B to W of the digital potentiometer divided by RSET.

NEGATIVE REFERENCE
Without using any matching resistors, a negative reference can be configured as shown in Figure 39. For the ADR01, the voltage difference between VOUT and GND is 10 V. Because VOUT is at virtual ground, U2 closes the loop by forcing the GND pin to be the negative reference node. U2 should be a precision op amp with a low offset voltage characteristic.

To optimize the resolution of this circuit, dual-supply op amps should be used because the ground potential of ADR02 can swing from -5 V at zero scale to VL at full scale of the potentiometer setting. latter is true, oscillation may occur. For this reason, a capacitor, C1, in the range of 1 pF to 10 pF should be connected between VP and the output terminal of U4, to filter any oscillation.

PROGRAMMABLE 4 TO 20 mA CURRENT TRANSMITTER
Because of their precision, adequate current handling, and small footprint, the devices are suitable as the reference sources for many high performance converter circuits. One of these applications is the multichannel 16-bit 4 to 20 mA current transmitter in the industrial control market (see Figure 42). This circuit employs a Howland current pump at the output, which yields better efficiency, a lower component count, and a higher voltage compliance than the conventional design with op amps and MOSFETs. In this circuit, if the resistors are matched such that R1 = R1, R2 = R2, R3 = R3, the load current is
(3)
In this circuit, an ADR01 provides the stable 10.000 V reference for the AD5544 quad 16-bit DAC. The resolution of the adjustable current is 0.3 A/step, and the total worst-case INL error is merely 4 LSB. Such error is equivalent to 1.2 A or a 0.006% system error, which is well below most systems' requirements. The result is shown in Figure 43 with measurement taken at 25C and 70C; total system error of 4 LSB at both 25C and 70C.

where D is similarly the decimal equivalent of the DAC input code and N is the number of bits of the DAC. According to Equation 2, R3 can be used to set the sensitivity. R3 can be made as small as necessary to achieve the current needed within U4 output current driving capability. On the other hand, other resistors can be kept high to conserve power.

Precision Boosted Output Regulator
A precision voltage output with boosted current capability can be realized with the circuit shown in Figure 44. In this circuit, U2 forces VO to be equal to VREF by regulating the turn-on of N1, thereby making the load current furnished by VIN. In this configuration, a 50 mA load is achievable at VIN of 15 V. Moderate heat is generated on the MOSFET, and higher current can be achieved with a replacement of a larger device. In addition, for a heavy capacitive load with a fast edging input signal, a buffer should be added at the output to enhance the transient response.

In this circuit, the AD8512 is capable of delivering 20 mA of current, and the voltage compliance approaches 15 V. The Howland current pump yields a potentially infinite output impedance, which is highly desirable, but resistance matching is critical in this application. The output impedance can be determined using Equation 3. As can be seen by this equation, if the resistors are perfectly matched, ZO is infinite. On the other hand, if they are not matched, ZO is either positive or negative. If the
