Description
The TSV85x, TSV85xA series of single, dual, and
quad operational amplifiers offer low voltage
operation with a rail-to-rail output swing. The
TSV85x, TSV85xA series outperforms the
industry standard LMV321, proposing lower
supply voltage capability, enhanced input offset
voltage, and smaller packages.
The devices are offered with either industry
standard pinouts or with a power-saving
shutdown feature that reduces the supply current
to a maximum of 50 nA at 25 °C.
The wide temperature range, high ESD tolerance,
and automotive grade qualification ease the use
in harsh automotive applications.
