Description
The TSV85x series of single, dual and quad
operational amplifiers offers low voltage operation
with a rail-to-rail output swing. The TSV85x series
outperforms the industry standard LMV321,
proposing lower supply voltage capability,
enhanced input offset voltage and smaller
packages.
SO8
SO14
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.
