The AD8047 and AD8048’s low distortion and cap load drive

make the AD8047/AD8048 ideal for buffering high speed ADCs.

They are suitable for 12-bit/10 MSPS or 8-bit/60 MSPS ADCs.

Additionally, the balanced high impedance inputs of the voltage

feedback architecture allow maximum flexibility when designing

active filters.

The AD8047 and AD8048 are offered in industrial (–40°C to

+85°C) temperature ranges and are available in 8-lead PDIP

and SOIC packages.

PRODUCT DESCRIPTION

The AD8047 and AD8048 are very high speed and wide band-

width amplifiers. The AD8047 is unity gain stable. The AD8048 is

stable at gains of two or greater. The AD8047 and AD8048,

which utilize a voltage feedback architecture, meet the require-

ments of many applications that previously depended on current

feedback amplifiers.

A proprietary circuit has produced an amplifier that combines

many of the best characteristics of both current feedback and

voltage feedback amplifiers. For the power (6.6 mA max), the

AD8047 and AD8048 exhibit fast and accurate pulse response

(30 ns to 0.01%) as well as extremely wide small signal and large

signal bandwidth and low distortion. The AD8047 achieves

–54 dBc distortion at 20 MHz, 250 MHz small signal, and

130 MHz large signal bandwidths.
