PRODUCT DESCRIPTION
The AD8042 is a low power voltage feedback, high speed am-
plifier designed to operate on +3 V, +5 V or
±
5 V supplies. It
has true single supply capability with an input voltage range
extending 200 mV below the negative rail and within 1 V of the
positive rail.

The output voltage swing extends to within 30 mV of each rail,
providing the maximum output dynamic range. Additionally, it
features gain flatness of 0.1 dB to 14 MHz while offering differ-
ential gain and phase error of 0.04% and 0.06
°
on a single +5 V
supply. This makes the AD8042 useful for professional video
electronics such as cameras, video switchers or any high speed
portable equipment. The AD8042’s low distortion and fast
settling make it ideal for buffering single supply, high speed
A-to-D converters.
The AD8042 offers low power supply current of 12 mA max
and can run on a single +3.3 V power supply. These features are
ideally suited for portable and battery powered applications
where size and power are critical.
The wide bandwidth of 160 MHz along with 200 V/
μ
s of slew
rate on a single +5 V supply make the AD8042 useful in many
general purpose, high speed applications where single supplies
from +3.3 V to +12 V and dual power supplies of up to
±
6 V
are needed. The AD8042 is available in 8-lead plastic DIP and
SOIC.
