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 10.8pA/√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 –78-dBc total harmonic distortion driving 2 VPP into a 100- load. The THS3115 features a low-power shutdown mode, consuming only 300-μA shutdown quiescent current per channel. The THS3112/5 are packaged in standard SOIC, SOIC PowerPAD?, and TSSOP PowerPAD packages.
