500-ma High-power Output Current Feedback Amplifier

Manufacturer: Texas Instruments

THS3491 Overview

The THS3491 current feedback amplifier (CFA) provides a new level of performance for applications requiring the lowest distortion at high output power levels from DC through values greater than 100 MHz at 100-Ω loads. Although specified at a gain of 5 V/V, this current feedback design holds near constant bandwidth and distortion over a wide range of gains. The 8000 V/µs of slew rate delivers an output of 10 VPP into...
