OPA4684 Datasheet (Texas Instruments) - Current-Feedback Operational Amplifier

OPA4684, Current-Feedback Operational Amplifier

The OPA4684 provides a new level of performance in lowpower, wideband, current-feedback (CFB) amplifiers.

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