OPA365 datasheet



The OPAx365 zer∅-crossover series, rail-to-rail, high performance, CMOS operational amplifiers are optimized for very low voltage, single-supply applications. Rail-to-rail input/output, low-noise (4.5nV/√Hz) and high-speed operation (50MHz Gain Bandwidth) make these devices ideal for driving sampling analog-to-digital converters (ADCs). Applications incude audio, signal conditioning, and sensor amplification. The OPA365 family of op amps are also well-suited for cell phone power amplifier control loops.

Special features include an excellent common-mode rejection ratio (CMRR), no input stage crossover distortion, high input impedance, and rail-to-rail input and output swing. The input common-mode range includes both the negative and positive supplies. The output voltage swing is within 10mV of the rails.
