DESCRIPTION

The OPAx365 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 analog-to-digital converters

(ADCs). Applications include 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 10 mV of the rails.

The OPA365 (single version) is available in the SOT23-5 package. The OPA2365 (dual version) is available in

the SO-8 package. All versions are specified for operation from

−40°C to 125°C. Single and dual versions have

identical specifications for maximum design flexibility.
