OPA350UA General Description

The OPA350UA is a high-speed, low-power operational amplifier manufactured by Texas Instruments. It has a wide bandwidth of 45 MHz and a fast slew rate of 20 V/µs, making it suitable for applications requiring fast signal processing. The OPA350UA operates on a low supply voltage range of 2.5V to 5.5V and consumes low quiescent current of 1.1 mA, making it ideal for battery-powered applications.This operational amplifier has a high open-loop gain of 100 dB and a high common-mode rejection ratio of 100 dB, ensuring accurate and precise signal amplification. It also features a low input offset voltage of 150 µV and a low input bias current of 1 pA, minimizing errors in signal processing.Furthermore, the OPA350UA comes in a small outline package (SOIC-8) for easy integration into various circuit designs.
