8.1 Overview
The OPAx365-Q1 zero-crossover family of rail-to-rail, high-performance, CMOS operational amplifiers are
optimized for very low voltage, single-supply applications. Their rail-to-rail input and output, low-noise (4.5
nV/√Hz), and high-speed operation (50-MHz gain bandwidth) make these devices ideal for driving sampling
analog-to-digital converters (ADCs). Applications include audio, signal conditioning, and sensor amplification. The
high-gain bandwidth of 50 MHz makes this family suited for amplifying low signal levels and high frequency such
as radar signal processing .
