Application information

4.1

Operating voltages

The TSV63x and TSV63xA can operate from 1.5 to 5.5 V. Their parameters are fully

specified for 1.8 V, 3.3 V, and 5 V power supplies. However, the parameters are very

TSV63xA characteristics at 1.5 V. Additionally, the main specifications are guaranteed in

extended temperature ranges from -40 °C to 125 °C.

4.2

Rail-to-rail input

The TSV63x and TSV63xA 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

at (VCC+) - 0.7 V. In the transition region, the performance of CMRR, PSRR, Vio

(Figure 16 and Figure 17), and THD is slightly degraded.

voltage at VCC = 1.5 V

voltage at VCC = 5 V

The devices are guaranteed without phase reversal.

Rail-to-rail output

The operational amplifiers’ output levels can go close to the rails: 35 mV maximum above

and below the rail when connected to a 10

kΩ resistive load to V
