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 45μA, the OPA348 series is useful for low-
power applications on single supplies of 2.1V to 5.5V.
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 detectors 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 extended temperature range of
–40°C to +125°C over all supply voltages offers
additional design flexibility.
