Application information
Operating voltages
The TSV630 and TSV631 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
Additionally, the main specifications are guaranteed in extended temperature ranges from -
40° C to +125° C.
Rail-to-rail input
The TSV630 and TSV631 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

The device is guaranteed without phase reversal.
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
