The THS4031 and THS4032 are ultralow-voltage
noise, high-speed voltage feedback amplifiers that
are ideal 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 100-MHz
bandwidth (G = 2), 100-V/ms slew rate, and 60-ns
settling time (0.1%). The THS4031 and THS4032 are
unity gain stable with 275-MHz bandwidth. These
amplifiers have a high drive capability of 90 mA and
draw only 8.5-mA supply current per channel. With
–90 dBc of total harmonic distortion (THD) at f = 1
MHz and a very low noise of 1.6 nV/√Hz, the
THS4031 and THS4032 are ideally suited for
applications requiring low distortion and low noise
such as buffering analog-to-digital converters.
