The ADA4850-1/ADA4850-2 are low price, high speed, voltage feedbacks rail-to-rail output op amps with ultralow power-down current. The output voltage swings to within 80 mV of either rail, and it is ideal for applications such as portable multimedia players, video cameras, digital still cameras, consumer video and clock buffers.
The ADA4850‑1 and ADA4850‑2 are low‑price, high‑speed voltage‑feedback op‑amps offering rail‑to‑rail output and single‑supply operation from 2.7 V to 6 V. They provide a –3 dB bandwidth of up to 175 MHz, a slew rate of 220 V/µs, and an output swing within 80 mV of either rail, making them suitable for video and multimedia applications.
The datasheet includes detailed specifications, absolute maximum ratings, thermal resistance data, pin configurations, and typical performance graphs for various supply voltages and loads. It also contains application notes for portable multimedia players, video cameras, and clock buffers.
