DESCRIPTION
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 45
μ
A, the
OPA348 series is useful for low-power applications on single
supplies of 2.1V to 5.5V.
Low supply current of 45
μ
A, 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.
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.
