LOW POWER, SINGLE-SUPPLY, RAIL-TO-RAIL

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

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).

MSOP-8

TSSOP-14

● 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 applications 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

A variety of packages are available. All are specified for

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

design analysis is available for download from www.ti.com.

● THD + NOISE: 0.006%
