DESCRIPTION

The OPAx365 zer

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 operations (50MHz Gain Bandwidth) make

them ideal for driving sampling analog-to-digital con-

verters (ADCs). Applications incude audio, signal con-

ditioning, and sensor amplification. The OPA365 family

of op amps are well-suited for cell phone power amplifi-

er control loops.

Special features include excellent common-mode re-

jection 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 microSIZE DFN-8 (3mm

x 3mm) and SO-8 packages. All versions are specified

for operation from −40

°C to +125°C. Single and dual

versions have identical specifications for maximum de-

sign flexibility.
