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

stable in the full VCC range and several characterization curves show the TSV63x and

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

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

(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

CC/2.
