1µA, Rail-to-Rail, CMOS

OPERATIONAL AMPLIFIERS

DESCRIPTION

FEATURES

The OPA349 and OPA2349 are ultra-low power op-

erational amplifiers that provide 70kHz bandwidth

with only 1µA quiescent current. These rail-to-rail

input and output amplifiers are specifically designed

for battery powered applications. Unlike some

micropower op amps, these parts are unity-gain stable

and require no external compensation. The OPA349’s

low input bias current allows the use of large source

and feedback resistors. The input common-mode volt-

age range extends 200mV beyond the power supply

rails and the output swings to within 150mV of the

rails, maintaining wide dynamic range.

● LOW SUPPLY CURRENT: 1µA

● GAIN-BANDWIDTH: 70kHz

● UNITY GAIN STABLE

● LOW INPUT BIAS CURRENT: 10pA

● WIDE SUPPLY RANGE: 1.8V to 5.5V

● INPUT RANGE 200mV BEYOND RAILS

● OUTPUT SWINGS TO 150mV OF RAILS

● OUTPUT DRIVE CURRENT: 20mA

● OPEN-LOOP GAIN: 90dB

● SOT23 MicroPACKAGES

OPA349 can be operated with power supplies from

1.8V to 5.5V with little change in performance, guar-

anteeing continuing superior performance even in low

battery situations.

APPLICATIONS

● BATTERY PACKS AND POWER SUPPLIES

● PORTABLE PHONES/PAGERS/CAMERAS

● SOLAR-POWERED SYSTEMS

● SMOKE/GAS/FIRE DETECTION SYSTEMS

● REMOTE SENSORS

● PCMCIA CARDS

● DRIVING A/D CONVERTERS

● MicroPOWER FILTERS

OPA349 comes in the miniature SOT23-5, SO-8 sur-

face mount and PDIP-8⁽¹⁾packages. OPA2349 dual is

also available in the SOT23 (8-lead SOT23-8), as well

as the SO-8 surface mount packages. These tiny pack-

ages are ideal for use in high-density applications,

such as PCMCIA cards, battery packs and portable

instruments.

All models are specified for the commercial tempera-

ture range, 0°C to +70°C.
