3 Description
The OPAx365-Q1 zero-crossover family, rail-to-rail,
high-performance, CMOS operational amplifiers are
optimized for very low voltage, single-supply
applications. Rail-to-rail input/output, low noise (4.5
nV/√Hz) and high speed operation (50-MHz gain
bandwidth) make these devices ideal for driving
sampling data converters (such as the ADS7822-Q1
or the ADS1115-Q1), specifically in short to mid-
range radar applications. The OPAx356-Q1 family of
operational amplifiers are also well-suited for HEV/EV
and Powertrain applications in DC-DC converters and
as transmission control in engine control units.
