This CFBPLUS amplifier is among the first to use an internally closed-loop input buffer stage that significantly enhances performance over earlier The output capability for the OPA2683 also sets a new mark in low-power, current-feedback (CFB) amplifiers. This new archiDataShee performance for very low-power, current-feedback amplifiers. Detecture provides many of the advantages of a more ideal CFB livering a full ±4VPP swing on ±5V supplies, the OPA2683 also has amplifier while retaining the benefits of very low-power operation. DataSheet4U.com the output current to support this swing into a 100Ω load. This The closed-loop input stage buffer gives a very low and linearized minimal output headroom requirement is complemented by a impedance path...
