OPERATIONAL AMPLIFIERS

FEATURES

DESCRIPTION

● LOW I_Q: 45µA typical

The OPA348 series amplifiers are single supply, low-power,

CMOS op amps in micro packaging. Featuring an extended

bandwidth of 1MHz, and a supply current of 45µA, the

OPA348 series is useful for low-power applications on single

supplies of 2.1V to 5.5V.

● LOW COST

● RAIL-TO-RAIL INPUT AND OUTPUT

● SINGLE SUPPLY: +2.1V to +5.5V

● INPUT BIAS CURRENT: 0.5pA

Low supply current of 45µA, and an input bias current of

0.5pA, make the OPA348 series an optimal candidate for

low-power, high-impedance applications such as smoke de-

tectors and other sensors.

● MicroSIZE PACKAGES: SC70-5, SOT23-8 and

TSSOP-14

● HIGH SPEED:POWER WITH BANDWIDTH: 1MHz

The OPA348 is available in the miniature SC70-5,

SOT23-5 and SO-8 packages. The OPA2348 is available in

SOT23-8 and SO-8 packages, and the OPA4348 is offered

in space-saving TSSOP-14 and SO-14 packages. The ex-

tended temperature range of –40°C to +125°C over all supply

voltages offers additional design flexibility.

APPLICATIONS
