DESCRIPTION
The OPAx348 series amplifiers are single-supply low-power CMOS operational amplifiers. Featuring an extended
bandwidth of 1 MHz and a supply current of 45 µA, the OPAx348 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 an optimal candidate for
low-power high-impedance applications such as smoke detectors and other sensors.
The OPA2348 is available in the SOIC-8 (D) package, and the OPA4348 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.
