Application information TSV611, TSV611A, TSV612, TSV612A 3 Application information 3.1 Operating voltages The TSV61x can operate from 1.5 to 5.5 V. The parameters are fully specified for 1.8, 3.3, and 5 V power supplies. However, the parameters are very stable in the full V range and CC 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 (V ) - 0.1 V to (V ) + 0.1 V. The transition between the two pairs appears at CC- CC+ (V ) - 0.7 V. In the transition region, the performance of CMRR, PSRR, V and THD is CC+ io slightly degraded (as shown in Figure 17 and Figure 18 for V vs. V ). io icm Figure 17.

TSV611, TSV611A, TSV612, TSV612A Application information 3.4 Driving resistive and capacitive loads These products are micro-power, low-voltage operational amplifiers optimized to drive rather large resistive loads, above 10 kΩ. 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 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 Ω) (or st si e s r e eri s n- I 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. DocID15768 Rev 3 13/21 21
