Description
The OPA365 and OPA2365 (OPAx365) zerøcrossover series, rail-to-rail, high-performance, CMOS operational amplifiers are optimized for very low
R2 2kΩ
voltage, single-supply applications.Rail-to-rail input or output, low-noise (4.5 nV/√Hz), and high-speed operation (50-MHz gain bandwidth) make these devices an excellent choice for driving sampling analog-to-digital converters (ADCs).Applications include audio, signal conditioning, and sensor amplification.Special
