The OPAx348 series of 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
series is useful for low-power applications on single supplies of 2.1 V to 5.5 V.
A low supply current of 45 µA and an input bias current of 0.5 pA, makes the OPAx348
series an optimal candidate for low-power applications such as smoke detectors and other
The OPA348 is available in the miniature 5-pin SC70 (SOT), 5-pin SOT-23 (SOT), and 8-pin
SO (SOIC) packages. The OPA2348 is available in 8-pin SOT-23 (SOT) and 8-pin SO (SOIC) packages,
and the OPA4348 is offered in space-saving 14-pin TSSOP and 14-pin SO (SOIC) packages. The extended
temperature range of 40°C to +125°C over all supply voltages offers design flexibility.
