描述 The OPA2348 is a single-supply low-power CMOS operational amplifier. Featuring an extended bandwidth of 1 MHz and a supply current of 45 µA, the OPA2348 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 OPA2348 an optimal candidate for low-power high-impedance applications such as smoke detectors and other sensors.特性 0°C to 70°C Known Good Die Separated (Sawn) Die Mounted on Wafer Tape Controlled Baseline Low Quiescent Current (IQ): 45 µA (Typ) Low Cost Rail-to-Rail Input and Output Single Supply: 2.1 V to 5.5 V Input Bias Current: 0.5 pA (Typ) High Speed:Power With Bandwidth: 1 MHz APPLICATIONS Portable Equipment Battery-Powered Equipment Smoke Alarms CO Detectors Medical Instrumentation
