The OPA2683 provides a new level of performance for dual, very low-power, wideband, current-feedback amplifiers. This CFBPLUS amplifier is among the first to use an internally closed-loop input buffer stage that significantly enhances performance over earlier low-power, current-feedback (CFB) amplifiers. This new architecture provides many of the advantages of a more ideal CFB amplifier while retaining the benefits of very low-power operation. 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 gives exceptional bandwidth retention to much higher gains and improved harmonic distortion over earlier solutions limited by inverting input linearity. Beyond simple high gain applications, the OPA2683 CFBPLUS amplifier can allow the gain setting element to be set with considerable freedom from amplifier bandwidth interaction. This
