Application information
Operating voltages
The TSV61x 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 TSV61x characteristics at 1.5 V. Additionally, the
main specifications are guaranteed in extended temperature ranges from -40° C to +85° C.
Rail-to-rail input
The TSV61x 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
(as shown in
The device is guaranteed without phase reversal.
Rail-to-rail output
The operational amplifiers’ output levels can go close to the rails: less than 35 mV above
GND rail and less than 35 mV below V
Driving resistive and capacitive loads
These products are micro-power, low-voltage operational amplifiers optimized to drive rather
large resistive loads, above 10 kΩ . For lower resistive loads, the THD level may significantly
increase.
