TSV62x, TSV62xA

Application information

4.1

Operating voltages

The TSV62x/TSV62xA can operate from 1.5 to 5.5 V. 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 is built with two complementary PMOS and NMOS input differential

pairs. The device has 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.
