3 Description
The OPAx348-Q1 series of devices 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 both the
SOT23-5 (DBV) and the SOIC (D) packages. 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.
