The OPA4347UA/2K5 is a micropower, rail-to-rail operational amplifier from Texas Instruments, designed for low-power applications. It operates with a single supply voltage ranging from 2.3V to 5.5V and features a low quiescent current of 20¬µA per amplifier, making it suitable for battery-powered devices. The amplifier has a bandwidth of 350kHz and provides rail-to-rail input and output, allowing for maximum signal swing. It is available in a 14-pin SOIC package and is specified for operation over a temperature range of -55¬8C to +125¬8C. The OPA4347 is ideal for applications such as portable equipment, smoke detectors, and two-wire transmitters, where low power consumption and compact size are critical.
