DESCRIPTION
The OPAx365 zer∅-crossover series, rail-to-rail, high-
performance, CMOS operational amplifiers are opti-
mized 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-digi-
tal converters (ADCs). Applications incude audio, sig-
nal 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 distor-
tion, high input impedance, and rail-to-rail input and out-
put swing. The input common-mode range includes
both the negative and positive supplies. The output volt-
age 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 ver-
sions are specified for operation from −40°C to +125°C.
Single and dual versions have identical specifications
for maximum design flexibility.
