DESCRIPTION
OPA350 series rail-to-rail CMOS operational amplifiers are
optimized for low voltage, single-supply operation. Rail-to-
rail input/output, low noise (5nV/√Hz), and high speed opera-
tion (38MHz, 22V/µs) make them ideal for driving sampling
Analog-to-Digital (A/D) converters. They are also well suited
for cell phone PA control loops and video processing (75Ω
drive capability) as well as audio and general purpose appli-
cations. Single, dual, and quad versions have identical speci-
fications for maximum design flexibility.
The OPA350 series operates on a single supply as low as 2.5V
with an input common-mode voltage range that extends

300mV below ground and 300mV above the positive supply.
Output voltage swing is to within 10mV of the supply rails with
a 10kΩ load. Dual and quad designs feature completely inde-
pendent circuitry for lowest crosstalk and freedom from inter-
action.
The single (OPA350) and dual (OPA2350) come in the
miniature MSOP-8 surface mount, SO-8 surface mount,
and DIP-8 packages. The quad (OPA4350) packages are
the space-saving SSOP-16 surface mount and SO-14 sur-
face mount. All are specified from –40°C to +85°C and
operate from –55°C to +150°C.
