THS4130ID

THS4130ID Description

The THS4130ID from Texas Instruments is a high-performance, fully differential amplifier designed for precision signal conditioning in demanding applications. Operating over a wide supply voltage range of 4V to 33V, this IC delivers exceptional performance with a 225 MHz gain bandwidth product (GBW) and a 150 MHz -3dB bandwidth, making it ideal for high-speed analog systems. Its 52V/µs slew rate and 85 mA output current capability ensure robust signal integrity, even in dynamic environments. The THS4130ID features low input bias current (2 µA) and minimal input offset voltage (200 µV), enhancing accuracy in sensitive circuits. Packaged in an 8-pin SOIC tube, this obsolete but RoHS3-compliant amplifier remains a reliable choice for legacy designs.
