THS3112 Datasheet Current Feedback Amplifiers

Manufacturer: Texas Instruments

Overview: THS3112 THS3115 www.ti.com SLOS385C – SEPTEMBER 2001 – REVISED SEPTEMBER 2010 LOW-NOISE, HIGH-SPEED, CURRENT FEEDBACK AMPLIFIERS Check for Samples: THS3112,.

General Description

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.
