AD811 Rev.E is a high-performance video op amp with features such as high speed bandwidth, low noise, low distortion, and flexible operation. This product is suitable for applications such as video crosspoint switchers, multimedia broadcast systems, HDTV compatible systems, and video line drivers.
The AD811 is a wideband current‑feedback operational amplifier optimized for broadcast‑quality video applications. It offers a 3 dB bandwidth of up to 140 MHz at unity gain, a slew rate exceeding 2500 V/µs, and very low voltage‑noise (1.9 nV/√Hz) and distortion, making it suitable for high‑frequency video signal paths.
Typical applications include video cross‑point switchers, HDTV broadcast systems, medical ultrasound, PET and gamma‑ray detectors, and high‑speed ADC/DAC buffering. The datasheet also provides ordering information for multiple package options and detailed electrical characteristics.
