The THS4031ID is a single ultralow-voltage noise high-speed voltage-feedback Operational Amplifier offers very good AC performance with 100MHz bandwidth (G=2), 100V/μs slew rate and 60ns settling time (0.1%). The THS4031 is unity gain stable with 275MHz bandwidth. This amplifier has a high drive capability of 90mA and draw only 8.5mA supply current per channel. With -90dBc of total harmonic distortion (THD) at f=1MHz and a very low noise of 1.6nV/√Hz, the THS4031 is ideally suited for applications requiring low distortion and low noise such as buffering analog-to-digital converters.
