Operational Amplifiers

FEATURES

ꢀ LOW I_Q: 20µA

DESCRIPTION

The OPA347 is a microPower, low-cost operational amplifier

available in micropackages. The OPA347 (single version) is

available in the SC-70 and SOT23-5 packages. The OPA2347

(dual version) is available in the SOT23-8 and WCSP-8

packages. Both are also available in the SO-8. The OPA347

is also available in the DIP-8. The OPA4347 (quad) is

available in the SO-14 and the TSSOP-14.

ꢀ microSIZE PACKAGES: WCSP-8, SC70-5

SOT23-5, SOT23-8, and TSSOP-14

ꢀ HIGH SPEED/POWER RATIO WITH

ꢀBANDWIDTH: 350kHz

ꢀ RAIL-TO-RAIL INPUT AND OUTPUT

ꢀ SINGLE SUPPLY: 2.3V to 5.5V

The small size and low power consumption (34µA per chan-

nel maximum) of the OPA347 make it ideal for portable and

battery-powered applications. The input range of the OPA347

extends 200mV beyond the rails, and the output range is

within 5mV of the rails. The OPA347 also features an

excellent speed/power ratio with a bandwidth of 350kHz.

APPLICATIONS

ꢀꢀPORTABLE EQUIPMENT

ꢀꢀBATTERY-POWERED EQUIPMENT

ꢀꢀ2-WIRE TRANSMITTERS

ꢀꢀSMOKE DETECTORS

The OPA347 can be operated with a single or dual power

supply from 2.3V to 5.5V. All models are specified for

operation from –55°C to +125°C.
