Texas Instruments OPA347 Micropower Rail-To-Rail Operational Amplifier OPA347PAG4

The OPA347PAG4 is a microPower operational amplifier designed for low power consumption, with a quiescent current of 20¬µA per channel. It operates on a single supply voltage ranging from 2.3V to 5.5V and features rail-to-rail input and output capabilities, allowing for an input range that extends 200mV beyond the supply rails and an output range within 5mV of the rails. The amplifier has a bandwidth of 350kHz, making it suitable for applications requiring a high speed-to-power ratio. This device is available in an 8-PDIP package and is specified for operation across a wide temperature range of -55¬8C to +125¬8C. It is particularly well-suited for portable and battery-powered applications, such as smoke and CO detectors, due to its low power requirements and compact size. The OPA347PAG4 also demonstrates good performance characteristics, including low input offset voltage and high common-mode rejection ratio, making it a reliable choice for general-purpose amplification tasks.
