Application information

4.1

Operating voltages

The TSV629x can operate from 1.5 to 5.5 V. The devices’ 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 TSV629x 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 TSV629x 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 CMR, SVR, Vio (Figure 19 and Figure 20) and

THD is slightly degraded.

The devices are guaranteed without phase reversal.

4.3

Rail-to-rail output

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

below the rail when connected to a 10 k

Ω resistive load to VCC/2.
