Why this current-feedback amp earns its place on the BOM
The AD80106Z is a single-channel current-feedback operational amplifier from Analog Devices, built for applications where slew rate and bandwidth need to hold up independent of the gain setting. With an 800 V/µs slew rate and 230 MHz -3 dB bandwidth, it handles fast pulse edges in video distribution, ADC front-end buffering, and high-speed communications gain stages without the gain-bandwidth trade-off that limits voltage-feedback amps. The 200 mA output current per channel gives it enough drive for 50 Ω back-terminated lines or multiple flash ADC inputs on the same trace.
Supply rail and thermal envelope — what the 9 V to 12 V range actually means
The supply span is 9 V minimum to 12 V maximum — tighter than many general-purpose op-amps, so the design must commit to a single rail in that window. If the load is continuous near 200 mA, budget for a board-level thermal analysis.
