| (R) ISL60002 Data Sheet December 17, 2007 FN8082.13 Precision Low Power FGATM Voltage References The ISL60002 FGATM voltage references are very high precision analog voltage references fabricated in Intersil's proprietary Floating Gate Analog technology and feature low supply voltage operation at ultra-low 350nA operating current. Additionally, the ISL60002 family features guaranteed initial accuracy as low as 1.0mV and 20ppm/C temperature coefficient. The initial accuracy and temperature stability performance of the ISL60002 family, plus the low supply voltage and 350nA power consumption, eliminates the need to compromise thermal stability for reduced power consumption making it an ideal companion to high resolution, low power data conversion systems.

Shorting VOUT to VCC is not recommended due to risk of resetting the part. NOTES: 2. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in VOUT is divided by the temperature range: (-40C to +85C = +125C, or -40C to +105C = +145C for the ISL60002-33). 3. Thermal Hysteresis is the change in VOUT measured @ TA = +25C after temperature cycling over a specified range, TA, VOUT is read initially at TA = +25C for the device under test. The device is temperature cycled and a second VOUT measurement is taken at +25C. The difference between the initial VOUT reading and the second VOUT reading is then expressed in ppm. For TA = +125C, the device under is cycled from +25C to +85C to -40C to +25C, and for TA = +145C, the device under is cycled from +25C to +105C to -40C to +25C 4. Long term drift is logarithmic in nature and diminishes over time. Drift after the first 1000 hours will be approximately 10ppm. 7 FN8082.13 December 17, 2007 ISL60002 Typical Performance Characteristic Curves ISL60002, VOUT = 1.024V VIN = 3.0V, IOUT = 0mA, TA = +25C unless otherwise specified. 700 600 500 IIN (nA) 400 300 200 100 0 2.7 2.9 3.1 3.3 3.5 3.7 3.9 4.1 4.3 4.5 4.7 4.9 5.1 5.3 5.5 VIN (V) UNIT 3 350 UNIT 2 UNIT 1 IIN (nA) 300 250 200 150 100 2.7 2.9 3.1 3.3 3.5 3.7 3.9 4.1 4.3 4.5 4.7 4.9 5.1 5.3 5.5 VIN (V) -40C 500 450 400 +25C +85C FIGURE 1.

DIFFERENT VIN AT ROOM TEMPERATURE FIGURE 115. DIFFERENT VIN AT HIGH TEMPERATURE Applications Information FGA Technology The ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current. Essentially, the charge stored on a floating gate cell is set precisely in manufacturing. The reference voltage output itself is a buffered version of the floating gate voltage. The resulting reference device has excellent characteristics which are unique in the industry: very low temperature drift, high initial accuracy, and almost zero supply current. Also, the reference voltage itself is not limited by voltage bandgaps or zener settings, so a wide range of reference voltages can be programmed (standard voltage settings are provided, but customer-specific voltages are available). The process used for these reference devices is a floating gate CMOS process, and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry. While providing excellent accuracy, there are limitations in output noise level and load regulation due to the MOS device characteristics. These limitations are addressed with circuit techniques discussed in other sections. In particular, battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in Figure 116. Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty, providing the highest accuracy and lowest possible long term drift. Other reference devices consuming higher supply currents will need to be disabled in between conversions to conserve battery capacity. Absolute accuracy will suffer as the device is biased and requires time to settle to its final value, or, may not actually settle to a final value as power on time may be short.

This drift can be eliminated by leaving the power on continuously. The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits. The ISL60002 consumes extremely low supply current due to the proprietary FGA technology. Supply current at room temperature is typically 350nA, which is 1 to 2 orders of magnitude lower than competitive devices. Application circuits using battery power will benefit greatly from having an accurate, stable reference, which essentially presents no load to the battery. 32 FIGURE 116. Board Mounting Considerations For applications requiring the highest accuracy, board mounting location should be reviewed. Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses. It is normally best to place the device near the edge of a board, or the shortest side, as the axis of bending is most limited at that location. Obviously mounting the device on flexprint or extremely thin PC material will likewise cause loss of reference accuracy. FN8082.13 December 17, 2007 ISL60002 Noise Performance and Reduction The output noise voltage in a 0.1Hz to 10Hz bandwidth is typically 30VP-P. This is shown in the plot in the Typical Performance Curves. The noise measurement is made with a bandpass filter made of a 1 pole high-pass filter with a corner frequency at 0.1Hz and a 2-pole low-pass filter with a corner frequency at 12.6Hz to create a filter with a 9.9Hz bandwidth. Noise in the 10kHz to 1MHz bandwidth is approximately 400VP-P with no capacitance on the output, as shown in Figure 117. These noise measurements are made with a 2 decade bandpass filter made of a 1 pole highpass filter with a corner frequency at 1/10 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency. Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50VP-P using a 0.001F capacitor on the output. Noise in the 1kHz to 100kHz band can be further reduced using a 0.1F capacitor on the output, but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 0.1F capacitance load. For load capacitances above 0.001F the noise reduction network shown in Figure 118 is recommended. This network reduces noise significantly over the full bandwidth. As shown in Figure 117, noise is reduced to less than 40VP-P from 1Hz to 1MHz using this network with a 0.01F capacitor and a 2k resistor in series with a 10F capacitor. 400 CL = 0 350 NOISE VOLTAGE (VP-P) 300 250 200 150 100 50 0 1 10 100 1k 10k 100k CL = 0.001F CL = 0.1F CL = 0.01F AND 10F + 2k VIN AND VOUT (V) 3.0 2.5 2.0 UNIT 3 1.5 1.0 0.5 UNIT 2 UNIT 1 Turn-On Time The ISL60002 devices have ultra-low supply current and thus the time to bias up internal circuitry to final values will be longer than with higher power references. Normal turn-on time is typically 7ms. This is shown in Figure 119. Since devices can vary in supply current down to >300nA, turn-on time can last up to about 12ms. Care should be taken in system design to include this delay before measurements or conversions are started. 3.5 3.0 VIN 2.5 VIN AND VOUT (V) 2.0 UNIT 3 1.5 1.0 0.5 UNIT 1 UNIT 2 0 -1 1 3 5 TIME (ms) 7 9 11 3.5 VIN 0 -1 1 3 5 TIME (ms) 7 9 11 FIGURE 117.

The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures, take the total variation, (VHIGH - VLOW), and divide by the temperature extremes of measurement (THIGH - TLOW). The result is divided by the nominal reference voltage (at T = +25C) and multiplied by 106 to yield ppm/C. This is the "Box" method for specifying temperature coefficient. 2k FIGURE 118. 33 FN8082.13 December 17, 2007 ISL60002 Typical Application Circuits VIN = 3.0V R = 200 2N2905 VIN ISL60002 VOUT VOUT = 2.50V GND 2.5V/50mA 0.001F FIGURE 120.
