description
The THS4031 and THS4032 are ultralow-voltage
noise, high-speed voltage feedback amplifiers
that are idealforapplicationsrequiringlowvoltage
noise, including communication and imaging. The
single-amplifier THS4031 and the dual-amplifier
THS4032 offer very good ac performance with
100-MHz bandwidth, 100-V/µs slew rate, and
60-ns settling time (0.1%). The THS4031 and
THS4032 are stable at gains of 2 (–1) or greater.
These amplifiers have a high drive capability of
90 mA and draw only 8.5-mA supply current per
channel. With total harmonic distortion (THD) of
–72 dBc at f = 1 MHz, the THS4031 and THS4032
are ideally suited for applications requiring low
distortion.
