Dual, Current Feedback Low Power Op Amp

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 and features gain flatness of 0.1 dB to 40 MHz while offering differential gain and phase error of 0.02% and 0.02°. This makes the AD812 ideal for professional video electronics such as cameras and video switchers.

The AD812 offers low power of 4.0 mA per amplifier max (VS = +5 V) and can run on a single +3 V power supply. The outputs of each amplifier swing to within one volt of either supply rail to easily accommodate video signals of 1 Vp-p. Also, at gains of +2 the AD812 can swing 3 V p-p on a single +5 V power supply. All this is offered in a small 8-pin plastic DIP or 8-pin SOIC package. These features make this dual amplifier ideal for portable and battery powered applications where size and power is critical.

The outstanding bandwidth of 145 MHz along with 1600 V/µs of slew rate make the AD812 useful in many general purpose high speed applications where a single +5 V or dual power supplies up to ±15 V are available. The AD812 is available in the industrial temperature range of -40°C to +85°C.

Lead free package option available (AD812ARZ, AD812ARZ-REEL, AD812ARZ-REEL7).
