Current-feedback video operational amplifier provides wide bandwidth and high slew rate for video and data-acquisition signal paths. The amplifier supports 140 MHz small-signal bandwidth at unity gain and 120 MHz bandwidth at a gain of +2. It settles to 0.1% in 25 ns for a 2 V step and provides low distortion performance up to 10 MHz. It operates from dual supplies and can drive video loads with 0.01% differential gain and 0.01° differential phase into 150 Ω.
