The ADA4860-1 is a low cost, high speed, current feedback op amp that provides excellent overall performance.
The ADA4860-1 is a low‑cost, high‑speed current‑feedback operational amplifier offering an 800 MHz –3 dB bandwidth, 790 V/µs slew rate, and 8 ns settling time to 0.5 %. It operates from a wide supply range of 5 V to 12 V, draws only 6 mA quiescent current, and can deliver up to 25 mA output current, making it suitable for consumer and professional video, broadband video, ADC buffers, and active filters.
Packaged in a 6‑lead SOT‑23, the device works over –40 °C to +105 °C and includes a power‑down pin to reduce consumption to 0.25 mA. Detailed specifications, absolute maximum ratings, thermal resistance, and typical performance curves are provided for designers.
