OPERATIONAL AMPLIFIERS

™

MicroAmplifier Series

FEATURES

DESCRIPTION

The OPA344 and OPA345 series rail-to-rail CMOS

operational amplifiers are designed for precision, low-

power, miniature applications. The OPA344 is unity

gain stable, while the OPA345 is optimized for gains

greater than or equal to five, and has a gain-bandwidth

product of 3MHz.

● RAIL-TO-RAIL INPUT

● RAIL-TO-RAIL OUTPUT (within 1mV)

● LOW QUIESCENT CURRENT: 150µA typ

● MicroSIZE PACKAGES

SOT23-5

MSOP-8

TSSOP-14

The OPA344 and OPA345 are optimized to operate on

a single supply from 2.5V and up to 5.5V with an input

common-mode voltage range that extends 300mV

beyond the supplies. Quiescent current is only

250µA (max).

● GAIN-BANDWIDTH

OPA344: 1MHz, G ≥ 1

OPA345: 3MHz, G ≥ 5

Rail-to-rail input and output make them ideal for driving

sampling analog-to-digital converters. They are also well

suited for general purpose and audio applicaitons and

providing I/V conversion at the output of D/A converters.

Single, dual and quad versions have identical specs for

design flexibility.

● SLEW RATE

OPA344: 0.8V/µs

OPA345: 2V/µs

● THD + NOISE: 0.006%

A variety of packages are available. All are specified for

operation from –40ºC to 85ºC. A SPICE macromodel is

available for design analysis.
