PRODUCT DESCRIPTION

The AD8013 is a low power, single supply, triple video

amplifier. Each of the three amplifiers has 30 mA of output

current, and is optimized for driving one back terminated video

load (150

Ω) each. Each amplifier is a current feedback amp-

lifier and features gain flatness of 0.1 dB to 60 MHz while offering

differential gain and phase error of 0.02% and 0.06

°. This

makes the AD8013 ideal for broadcast and professional video

electronics.

The AD8013 offers low power of 4 mA per amplifier max and

runs on a single +5 V to +13 V power supply. The outputs of

each amplifier swing to within one volt of either supply rail to

easily accommodate video signals. The AD8013 is unique

among current feedback op amps by virtue of its large capacitive

load drive. Each op amp is capable of driving large capacitive

loads while still achieving rapid settling time. For instance it

can settle in 18 ns driving a resistive load, and achieves 40 ns

(0.1%) settling while driving 200 pF.

The outstanding bandwidth of 140 MHz along with 1000 V/

µs

of slew rate make the AD8013 useful in many general purpose

high speed applications where a single +5 V or dual power

supplies up to

±6.5 V are required. Furthermore the AD8013’s

high speed disable function can be used to power down the

amplifier or to put the output in a high impedance state. This

can then be used in video multiplexing applications. The

AD8013 is available in the industrial temperature range of

–40

°C to +85°C.
