OPA353UA Description

The OPA353UA from Texas Instruments is a high-performance, general-purpose operational amplifier (op-amp) belonging to the MicroAmplifier™ series. Designed for precision and speed, this single-channel op-amp operates over a 2.5V to 5.5V supply range, making it ideal for low-voltage applications. With a 44 MHz gain bandwidth product (GBW) and a 22V/µs slew rate, the OPA353UA delivers excellent dynamic performance for signal conditioning, filtering, and amplification tasks. Its ultra-low input bias current (0.5 pA) and 3 mV input offset voltage ensure high accuracy in sensitive circuits. Packaged in an 8-pin SOIC tube, this RoHS3-compliant device is suited for surface-mount designs in industrial, medical, and consumer electronics.
