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.
