SBOS213C – NOVEMBER 2001 – REVISED MAY 2002
1MHz, 45µA, CMOS, Rail-to-Rail
OPERATIONAL AMPLIFIERS
FEATURES
DESCRIPTION
● LOW IQ: 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.
