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.

Easy to Use

50 mA Output Current

Output Swing to 1 V of Rails

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 ampli-

fier swing to within one volt of either supply rail to easily accom-

modate 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-lead plastic DIP or SOIC package. These

features make this triple amplifier ideal for portable and battery

powered applications where size and power are critical.

APPLICATIONS

Video Line Driver

LCD Drivers

Computer Video Plug-In Boards

Ultrasound

RGB Amplifier

CCD Based Systems

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 avail-

able in the industrial temperature range of –40°C to +85°C in

plastic DIP and SOIC packages as well as chips.

PRODUCT DESCRIPTION

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 Ω). The AD813 features gain flatness of 0.1 dB to
