OPA2353UA General Description

The OPA2353UA is a precision operational amplifier manufactured by Texas Instruments. It features a low input offset voltage of 100µV (max), making it suitable for precision applications. With a low input bias current of 1pA (max), it minimizes errors in high-impedance circuits. The OPA2353UA operates over a wide supply voltage range of ±1.35V to ±18V, offering flexibility in various voltage configurations. It provides a high open-loop gain of 115dB (typ) and a unity-gain bandwidth of 3MHz, ensuring stable operation in a variety of signal processing tasks. The amplifier has rail-to-rail input and output capabilities, allowing it to handle signals close to the supply rails without distortion. Its low quiescent current of 725µA (max) makes it suitable for battery-powered applications, extending battery life. The OPA2353UA is available in a small outline package, making it suitable for space-constrained designs.
