Good Video Specifications (R_L= 150 ⍀, G = +2)

Gain Flatness of 0.1 dB to 14 MHz

0.02% Differential Gain Error

0.04؇ Differential Phase Error

Low Distortion

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.

APPLICATIONS

Video Switchers

Distribution Amplifiers

A/D Driver

Professional Cameras

CCD Imaging Systems

Ultrasound Equipment (Multichannel)

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/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 plastic DIP and

SOIC.

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.
