The AD813 is a low power, single supply triple video amplifier. Each of the three current feedback amplifiers has 50 mA of output current, and is optimized for driving one back terminated video load (150 W). The AD813 features gain flatness of 0.1 dB to 50 MHz while offering differential gain and phase error of 0.03% and 0.06°. This makes the AD813 ideal for broadcast and consumer video electronics.
The AD813 offers low power of 5.5 mA per amplifier max and runs 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. While operating on a single +5 V supply the AD813 still achieves 0.1 dB flatness to 20 MHz and 0.05% & 0.05° of differential gain and phase performance. All this is offered in a small 14-pin plastic DIP or SOIC package. These features make this triple amplifier ideal for portable and battery powered applications where size and power are critical.
The outstanding bandwidth of 125 MHz along with 500 V/µs of slew rate make the AD813 useful in many general purpose, high speed applications where a single +3 V or dual power supplies up to ±15 V are needed. Furthermore the AD813 contains a high speed disable function for each amplifier in order to power down the amplifier or high impedance the output. This can then be used in video multiplexing applications. The AD813 is available in the industrial temperature range of -40°C to +85°C in plastic DIP and SOIC packages as well as chips.
