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.
