OPA3684 - Operational Amplifier

General Description

The OPA3684 provides a new level of performance in low-power, wideband, current-feedback (CFB) amplifiers.

This CFBPLUS amplifier among the first to use an internally closed-loop input buffer stage that enhances performance significantly over earlier lowpower CFB amplifiers.

Key Features

  • igh Slew Rate CFB > 500MHz CFB Fixed-Gain Video Buffers.
