The AD812 is a low power, single supply, dual video amplifier. Each of the amplifiers have 50 mA of output current and are optimized for driving one back-terminated video load (150 Ω) each. Each amplifier is a current feedback amplifier.
The AD812 is a dual‑channel, low‑power current‑feedback operational amplifier designed for video applications. Each channel can deliver 50 mA into a 150 Ω load and operates from a single +3 V supply with a quiescent current of about 5.5 mA per amplifier.
Key features include 0.1 dB gain flatness to 40 MHz, a 1600 V/µs slew rate, and an operating temperature range of –40 °C to +85 °C. The device is supplied in 8‑lead plastic DIP and SOIC packages and is suitable for portable, battery‑powered video equipment.
