3 Description

The OPA350 series of rail-to-rail CMOS operational

amplifiers are optimized for low voltage, single-supply operation. Rail-to-rail input and output, low noise (5

nV/√Hz), and high speed operation (38 MHz, 22 V/μs)

make the amplifiers ideal for driving sampling Analog•

to-Digital (A/D) converters. They are also 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 2.5 V, with an input common-mode voltage

range that extends 300 mV below ground and 300

mV above the positive supply. Output voltage swing

is to within 10 mV of the supply rails, with a 10-kΩ

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 in 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.
