The devices also feature an ultra-low input bias current as well as a low input offset voltage. The TSV61x have a gain bandwidth product of 120 kHz while consuming only 10 A at 5 V. These features make the TSV61x family ideal for sensor interfaces, battery supplied and portable applications, as well as active filtering.

Their parameters are fully specified for 1.8, 3.3 and 5 V power supplies. However, the parameters are very stable in the full VCC range and several characterization curves show the TSV61x characteristics at 1.5 V. Additionally, the main specifications are guaranteed in extended temperature ranges from -40 C to +85 C. 3.2 Rail-to-rail input The TSV61x are built with two complementary PMOS and NMOS input differential pairs. The devices have a rail-to-rail input, and the input common mode range is extended from VCC- -0.1 V to VCC+ +0.1 V. The transition between the two pairs appears at VCC+ -0.7 V. In the transition region, the performance of CMRR, PSRR, Vio and THD is slightly degraded (as shown in Figure 17 and Figure 18 for Vio vs. Vicm). Figure 17. Input offset voltage vs input common mode at VCC = 1.5 V 1.5 1.0 Input Offset Voltage (mV) Figure 18.

When driving larger capacitive loads, adding an in-series resistor at the output can improve the stability of the devices (see Figure 19 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 19. In-series resistor vs. capacitive load 3.5 PCB layouts For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible to the power supply pins. 3.6 Macromodel An accurate macromodel of the TSV61x 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 TSV61x operational amplifiers. It emulates the nominal performances of a typical device within the specified operating conditions mentioned in the datasheet. It also helps to validate a design approach and to select the right operational amplifier, but it does not replace on-board measurements.
