Supply
The THS3112/5 are low-noise, high-speed current
feedback amplifiers, ideal for any application requiring
high output current. The low noninverting current noise
of 2.9 pA/√Hz and the low inverting current noise of 10.8
pA/√Hz increase signal to noise ratios for enhanced
signal resolution. The THS3112/5 can operate from
±5-V to ±15-V supply voltages, while drawing as little as
4.5 mA of supply current per channel. It offers low

100-Ω load. The THS3115 features a low power
shutdown mode, consuming only 300-µA shutdown
quiescent current per channel. The THS3112/5 is
packaged in a standard SOIC, SOIC PowerPAD , and
TSSOP PowerPAD packages.
