Application information
Operating voltages
The TSV63x 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
several characterization curves show the TSV63x characteristics at 1.5 V. Additionally, the
main specifications are guaranteed in extended temperature ranges from -40° C to +125° C.
Rail-to-rail input
The TSV63x 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 transition region, the performance of CMRR, PSRR, V
THD is slightly degraded.
The devices are 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
Shutdown function (TSV633 - TSV635)
The operational amplifiers are enabled when the SHDN pin is pulled high. To disable the
amplifiers, the SHDN must be pulled down to V
output is in a high impedance state. The SHDN pin must never be left floating, but tied to
