GENERAL DESCRIPTION
The AD8042 is a low power voltage feedback, high speed amplifier
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 differential
gain and phase error of 0.04% and 0.06° on a single 5 V supply.
This combination of features makes the AD8042 useful for
professional video electronics, such as cameras, video switchers,
or any high speed portable equipment. The low distortion and
fast settling of the AD8042 make it ideal for buffering single-
supply, high speed analog-to-digital converters (ADCs).
The AD8042 offers a low power supply current of 12 mA
maximum 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/μs 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 PDIP and 8-lead
SOIC_N packages.
