Medical Instrumentation DESCRIPTION
The OPA2348 is a single-supply low-power CMOS operational amplifier. Featuring an extended bandwidth of 1
MHz and a supply current of 45 ОјA, the OPA2348 is useful for low-power applications on single supplies of 2.1 V
to 5.5 V.
Low supply current of 45 ОјA and an input bias current of 0.5 pA make the OPA2348 an optimal candidate for
low-power high-impedance applications such as smoke detectors and other sensors.
