TSV621ICT/ILT SC70-5/SOT23-5
This operational amplifier is unity gain stable for capacitive loads up to 100 pF. The device is internally adjusted to provide very narrow dispersion of AC and DC parameters, especially power consumption, product gain bandwidth and slew rate. The TSV621 presents a high tolerance to ESD, sustaining 4 kV for the human body model. Additionally, the TSV621 is offered in SC70-5 and SOT23-5 micropackages, with extended temperature ranges from -40 C to +125 C. All these features make the TSV621 ideal for sensor interfaces, battery-supplied and portable applications, as well as active filtering.
Applications

Battery-powered applications Portable devices Signal conditioning Active filtering Medical instrumentation
Description
The TSV621 is a single operational amplifier offering low voltage, low power operation and railto-rail input and output. With a very low input bias current and low offset voltage (800 V maximum for the A version), the TSV621 is ideal for applications that require precision. The device can operate at a power supply ranging from 1.5 to 5.5 V, and therefore suits battery-powered devices and extends battery life. This product features an excellent speed/power consumption ratio, offering a 420 kHz gain bandwidth while consuming only 29 A at a 5-V supply voltage.

Application information
Operating voltages
The TSV621 can operate from 1.5 to 5.5 V. Its parameters are fully specified for 1.8-, 3.3and 5-V power supplies. However, the parameters are very stable in the full VCC range and several characterization curves show the TSV621 characteristics at 1.5 V. Additionally, the main specifications are guaranteed in extended temperature ranges from -40 C to +125 C.
3.2
Rail-to-rail input
The TSV621 is built with two complementary PMOS and NMOS input differential pairs. The device has a rail-to-rail input, and the input common mode range is extended from VDD -0.1 V to VCC +0.1 V. The transition between the two pairs appear at VCC -0.7 V. In the transition region, the performance of CMRR, PSRR, Vio and THD is slightly degraded (as shown in Figure 14 and Figure 15 for Vio vs. Vicm).

Rail-to-rail output
The operational amplifier's output level can go close to the rails: 35 mV maximum above and below the rail when connected to a 10 k resistive load to VCC/2.

Application information
3.4
Optimization of DC and AC parameters
This device uses an innovative approach to reduce the spread of the main DC and AC parameters. An internal adjustment achieves a very narrow spread of current consumption (29 A typical, min/max at 17%). Parameters linked to the current consumption value, such as GBP, SR and AVd benefit from this narrow dispersion. All parts present a similar speed and the same behavior in terms of stability. In addition, the minimum values of GBP and SR are guaranteed (GBP = 350 kHz min, SR = 0.15 V/s min).
3.5
Driving resistive and capacitive loads
These products are micro-power, low-voltage operational amplifiers optimized to drive rather large resistive loads, above 5 k For lower resistive loads, the THD level may significantly . increase. In a follower configuration, these operational amplifiers can drive capacitive loads up to 100 pF with no oscillations. When driving larger capacitive loads, adding a small in-series resistor at the output can improve the stability of the device (see Figure 16 for recommended in-series resistor values). Once the in-series resistor value has been selected, the stability of the circuit should be tested on bench and simulated with the simulation model. Figure 16. In-series resistor vs. capacitive load

PCB layouts
For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible to the power supply pins.

Macromodel
An accurate macromodel of TSV621 is available on STMicroelectronics' web site at www.st.com. This model is a trade-off between accuracy and complexity (that is, time simulation) of the TSV62x operational amplifiers. It emulates the nominal performances of a typical device within the specified operating conditions mentioned in the datasheet. It helps to validate a design approach and to select the right operational amplifier, but it does not replace on-board measurements.
