Application information

4.1

Operating voltages

TSV62x/TSV62xA devices 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/TSV62xA

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/TSV62xA 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.
