4 Application information
4.1 Operating voltages
The TSV63x and TSV63xA can operate from 1.5 to 5.5 V. Their parameters are fully
specified for 1.8 V, 3.3 V, and 5 V power supplies. However, the parameters are very
stable in the full V
CC
range and several characterization curves show the TSV63x and
TSV63xA 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 TSV63x and TSV63xA 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 (VCC+) - 0.7 V. In the transition region, the performance of CMRR, PSRR, Vio
(Figure 16 and Figure 17), and THD is slightly degraded.

voltage at VCC = 5 V
The devices are guaranteed without phase reversal.
4.3 Rail-to-rail output
The operational amplifiers’ output levels can go close to the rails: 35 mV maximum above
and below the rail when connected to a 10 kΩ resistive load to V
