DESCRIPTION
The THS4021 and THS4022 are ultralow voltage
noise, high-speed voltage feedback amplifiers that
are ideal for applications requiring low voltage noise,
including communication and imaging. The
single-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.
