description  
The THS4021 and THS4022 are ultra-low voltage  
noise, high-speed voltage feedback amplifiers  
that are idealforapplicationsrequiringlowvoltage  
noise, including communication and imaging. The  
signal-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.
