This allows frequency response peaking elements to be added, multiple The OPA2684 provides a new level of performance in lowinput inverting summing circuits to have greater bandwidth, power, wideband, current-feedback (CFB) amplifiers. This and low-power line drivers to meet the demanding requireCFBPLUS amplifier is among the first to use an internally ments of studio cameras and broadcast video. closed-loop input buffer stage that enhances performance The output capability of the OPA2684 also sets a new mark significantly over earlier low-power CFB amplifiers. While in performance for low-power, current-feedback amplifiers. retaining the benefits of very low power operation, this new DataShee Delivering a full ±4Vp-p swing on ±5V supplies, the OPA2684 architecture provides many of t...
