transimpedance linearization circuitry. This allows it to drive

video loads with excellent differential gain and phase perfor-

mance on only 50 mW of power. The AD8001 is a current

feedback amplifier and features gain flatness of 0.1 dB to 100 MHz

while offering differential gain and phase error of 0.01% and

0.025

°. This makes the AD8001 ideal for professional video

electronics such as cameras and video switchers. Additionally,

the AD8001’s low distortion and fast settling make it ideal for

buffer high speed A-to-D converters.

±5 V) and

can run on a single +12 V power supply, while being capable of

delivering over 70 mA of load current. These features make this

amplifier ideal for portable and battery-powered applications

where size and power are critical.

The outstanding bandwidth of 800 MHz along with 1200 V/

µs

of slew rate make the AD8001 useful in many general-purpose

high speed applications where dual power supplies of up to

±6 V

and single supplies from 6 V to 12 V are needed. The AD8001 is

available in the industrial temperature range of –40

°C to +85°C.
