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 V_CC 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 V_CC- - 0.1 V to V_CC+ + 0.1 V. The transition between the two pairs appears at
V_CC+ - 0.7 V. In the transition region, the performance of CMRR, PSRR, V_io (Figure 16 and
Figure 17) and THD is slightly degraded.

The devices are guaranteed without phase reversal.

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 kΩ resistive load to V_CC/2.
