OPA350UA

OPA350UA Description

The OPA350UA from Texas Instruments is a high-performance, general-purpose operational amplifier (op-amp) belonging to the MicroAmplifier™ series. Designed for precision analog applications, it features a 38 MHz gain bandwidth product (GBW), 22V/µs slew rate, and ultra-low 0.5 pA input bias current, making it ideal for high-speed, low-noise signal conditioning. Operating over a 2.5V to 5.5V supply range, it consumes 5.2mA supply current while delivering 40 mA output current. The device exhibits excellent DC precision with 150 µV input offset voltage and is available in an 8-pin SOIC package, ensuring compact PCB integration.
