The OPA365 and OPA2365 (OPAx365) zerø-crossover series, rail-to-rail, high-performance, CMOS operational amplifiers are optimized for very low 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 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 micro-size SOT23-5 (SOT-5) and SOIC-8 packages. The OPA2365 (dual version) is offered in the SOIC-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.
