These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
DESCRIPTION
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/µs 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.
