The current-feedback topology means the bandwidth holds up well as gain increases, unlike voltage-feedback amplifiers that trade gain for bandwidth. A 3500 V/µs slew rate lets this amplifier reproduce fast edges with minimal distortion. For a 10 V output step, the rise time is roughly 2.9 ns, making the part a fit for video line drivers (where 0.1 dB flatness to tens of MHz matters) and for driving the input of high-speed ADCs that need a clean, fast-settling signal. The 125 mA output current per channel provides enough drive to handle 50 Ω or 75 Ω back-terminated cables directly. ## Supply range and quiescent current The LT1228CS8#TRPBF operates from a 4 V to 36 V total supply span, covering both single-supply (e.g., 5 V or 12 V) and split-supply (e.g., ±5 V or ±15 V) rails. Quiescent current is 6 mA, which is moderate for a 3500 V/µs part — power-sensitive designs should weigh this against the slew-rate requirement. The 10 µA input bias current is typical for a current-feedback input stage. The 8-SOIC package (8-SO) is a standard surface-mount footprint, compatible with common PCB layouts and reflow processes. The -3 dB bandwidth and slew rate are specified across the full temperature range, but input offset voltage (3 mV max) and bias current may shift at the extremes. It is ROHS3 compliant.","metaTitle":"LT1228CS8#TRPBF Current Feedback Op-Amp, 3500V/µs Slew Rate","metaDescription":"LT1228CS8#TRPBF from Analog Devices: single current-feedback op-amp, 3500 V/µs slew rate, 100 MHz bandwidth, 8-SOIC.
