3 Description

The THS4031 and THS4032 (THS403x) are ultra-low voltage noise, high-speed voltage feedback amplifiers that are an excellent choice for applications requiring low voltage noise, including communications and imaging. The single-amplifier THS4031 and the dual-amplifier THS4032 offer very good ac performance with 100MHz bandwidth (G = 2), 100V/μs slew rate, and 70ns settling time (0.1%). The THS403x are unity-gain stable with 120MHz bandwidth. These amplifiers have a high drive capability of 200mA and draw only 7.5mA supply current per channel. With –96dBc of total harmonic distortion (THD) at f = 1MHz and a very low noise of 1.2nV/√Hz, the THS403x are designed for applications requiring low distortion and low noise such as buffering analog-to-digital converters.
