3 Description
The OPAx348-Q1 series of device are single-supply
low-power CMOS operational amplifiers. Featuring an
extended bandwidth of 1 MHz and a supply current of
45 µA, the OPAx348-Q1 family of devices is useful
for low-power applications on single supplies of 2.1 V
to 5.5 V.
Low supply current of 45 µA and an input bias current
of 0.5 pA make the OPAx348-Q1 family of devices an
optimal candidate for low-power high-impedance
applications such as smoke detectors and other
sensors.
The OPA348-Q1 device is available in the SOT23-5
(DBV) package. The OPA2348-Q1 device is available
in the SOIC-8 (D) package. The OPA4348-Q1 device
is available in the TSSOP-14 (PW) package. The
automotive temperature range of –40°C to 125°C
over all supply voltages offers additional design
flexibility.
