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.
The AD8001 offers low power of 5.5 mA max (VS =
±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.
