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.

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
