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 low power CFB amplifiers. While retaining the benefits of very low power operation, this new architecture provides many of the benefits of a more ideal CFB amplifier. The closed-loop input stage buffer gives a very low and linearized impedance path at the inverting input to sense the feedback error current. This improved inverting input impedance retains exceptional bandwidth to much higher gains and improves harmonic distortion over earlier solutions limited by inverting input linearity. Beyond simple high-gain applications, the OPA3684 CFBPLUS amplifier permits the gain setting element to be set with considerable freedom from amplifier bandwidth interaction.
