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 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.
