THS4131CDGN

THS4131CDGN Description

The THS4131CDGN from Texas Instruments is a high-performance, fully differential amplifier designed for precision signal conditioning in demanding applications. Packaged in an 8-HVSSOP tube, this IC operates over a 4V to 33V supply range, delivering exceptional performance with a 225 MHz gain bandwidth product (GBW) and a 150 MHz -3dB bandwidth. Its 52V/µs slew rate and 85 mA output current enable high-speed signal processing, while the 200 µV input offset voltage ensures accuracy. Although marked as obsolete, it remains a robust choice for legacy designs requiring low input bias current (2 µA) and ROHS3 compliance.
