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掳. This makes the AD8001 ideal for professional video
electronics such as cameras and video switchers. Additionally,
the AD8001鈥檚 low distortion and fast settling make it ideal for
buffer high-speed A-to-D converters.
The AD8001 offers low power of 5.5 mA max (V
S

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/碌s
of slew rate make the AD8001 useful in many general purpose
high-speed applications where dual power supplies of up to
卤
6 V
and single supplies from 6 V to 12 V are needed. The AD8001 is
available in the industrial temperature range of 鈥?0掳C to +85掳C.
The AD8001 is a low power, high-speed amplifier designed
to operate on
