The AD813 is a triple video amplifier with low power and high performance, suitable for video line driving, LCD driving, computer video plug-in boards, ultrasound RGB amplifier and CCD based systems.
The AD813 is a low‑power, single‑supply triple video amplifier designed for driving back‑terminated video loads (150 Ω). It integrates three current‑feedback amplifiers in a 14‑lead DIP or SOIC package, each delivering up to 50 mA output current and operating from +3 V to ±15 V supplies.
Key features include 0.1 dB gain flatness to 50 MHz, 125 MHz unity‑gain bandwidth, 500 V/µs slew rate, and per‑channel disable functions for power saving. The device is specified for industrial temperature ranges (‑40 °C to +85 °C) and is suitable for video line drivers, LCD drivers, computer video boards, and other high‑speed video applications.
| Gain Flatness | 0.1 dB to 50 MHz |
|---|---|
| Unity‑Gain Bandwidth (‑3 dB) | 125 MHz |
| Input Voltage Noise | 3.5 nV/√Hz |
| Input Current Noise | 1.5 pA/√Hz |
| Operating Temperature Range | ‑40 °C to +85 °C |
Each amplifier draws about 5.5 mA of quiescent current.
The device has a unity‑gain bandwidth of 125 MHz.
