DESCRIPTION

The

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 operation (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 (75

Ω drive capability)

as well as audio and general purpose applications. Single,

dual, and quad versions have identical specifications 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 10k

Ω load. Dual and quad designs

feature completely independent circuitry for lowest

crosstalk and freedom from interaction.

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

surface mount. All are specified from −40

°C to +85°C and

operate from −55

°C to +150°C.
