FEATURES

DESCRIPTION

The OPA348 series amplifiers are single supply, low-

2

•

power, CMOS op amps in micro packaging. Featuring

•

LOW COST

an extended bandwidth of 1MHz, and a supply

•

RAIL-TO-RAIL INPUT AND OUTPUT

current of 45

μA, the OPA348 series is useful for low-

power applications on single supplies of 2.1V to 5.5V.

•

SINGLE SUPPLY: +2.1V to +5.5V

•

INPUT BIAS CURRENT: 0.5pA

Low supply current of 45

μA, and an input bias current

of 0.5pA, make the OPA348 series an optimal

•

MicroSIZE PACKAGES:

candidate for low-power, high-impedance applications

SC70-5, SOT23-8 and TSSOP-14

such as smoke detectors and other sensors.

•

HIGH SPEED: POWER WITH BANDWIDTH:

The OPA348 is available in the miniature SC70-5,

1MHz

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

available in SOT23-8 and SO-8 packages, and the
