DESCRIPTION

OPA353 series rail-to-rail CMOS operational amplifiers

are designed for low cost, miniature applications.

They are optimized for low voltage, single-supply operation.

Rail-to-rail input/output, low noise (5nV/ÖHz),

and high speed operation (44MHz, 22V/ms) make them

ideal for driving sampling analog-to-digital converters.

They are also well suited for cell phone PA control

loops and video processing (75W drive capability) as

well as audio and general purpose applications. Single,

dual, and quad versions have identical specifications

for design flexibility.

The OPA353 series operates on a single supply as low as

2.5V with an input common-mode voltage range that

extends 300mV beyond the supply rails. Output voltage

swing is to within 10mV of the supply rails with a 10kW

load. Dual and quad designs feature completely independent

circuitry for lowest crosstalk and freedom from

interaction.

The single (OPA353) packages are the tiny 5-lead SOT-

23-5 surface mount and SO-8 surface mount. The dual

(OPA2353) comes in the miniature MSOP-8 surface

mount and SO-8 surface mount. The quad (OPA4353)

packages are the space-saving SSOP-16 surface mount

and SO-14 surface mount. All are specified from –40°C

to +85°C and operate from –55°C to +125°C.
