description

The THS4021 and THS4022 are ultra-low voltage

noise, high-speed voltage feedback amplifiers

that are ideal for applications requiring low voltage

noise, including communication and imaging. The

signal-amplifier THS4021 and the dual-amplifier

THS4022 offer very good ac performance with

350-MHz bandwidth, 470-V/

µs slew rate, and

40-ns settling time (0.1%). The THS4021 and

THS4022 are stable at gains of 10 (– 9) or greater.

These amplifiers have a high drive capability of

100 mA and draw only 7.8-mA supply current per

channel. With total harmonic distortion (THD) of

– 68 dBc at f = 1 MHz, the THS4021 and THS4022

are ideally suited for applications requiring low

distortion.
