THS4032IDR

The THS4031 and THS4032 (THS403x) are ultra-low voltage noise, high-speed voltage feedback amplifiers, ideal for applications requiring low voltage noise, including communications and imaging. The single-channel THS4031 and dual-channel THS4032 deliver AC performance with 100 MHz bandwidth (G = 2), 100 V/μs slew rate, and 70 ns settling time (0.1%). The THS403x offers unity-gain stability with 120 MHz bandwidth. These amplifiers feature 200 mA high drive capability while consuming only 7.5 mA supply current per channel. The THS403x achieves -96 dBc THD at f = 1 MHz and features 1.2 nV/√Hz ultra-low noise, designed for applications demanding low distortion and low noise, such as buffering ADCs.
