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.
