The 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/output, low-noise (4.5nV/√Hz) and high-speed operations (50MHz Gain Bandwidth) make them ideal for driving sampling analog-to-digital converters (ADCs). Applications incude audio, signal conditioning, and sensor amplification. The OPA365 family of op amps are well-suited for cell phone power amplifier control loops.
Special features include 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.
The OPA365 (single version) is available in the micro-SIZE SOT23-5 and SO-8 packages. The OPA2365 (dual version) is offered 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.
