Application information

4.1

Operating voltages

The TSV62x can operate from 1.5 to 5.5 V. 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 TSV62x 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 TSV62x 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.

The devices are guaranteed without phase reversal.

4.3

Rail-to-rail output

The operational amplifier’s 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.
