PRODUCT DESCRIPTION

The AD8024 is a low settling time, high-speed, high output

voltage quad current feedback operational amplifier. Manu-

factured on ADI’s proprietary XFHV high-speed bipolar process,

the AD8024 is capable of driving to within 1.3 V of its 24 V

supply rail. Each amplifier has high-output current capability

and can drive high capacitive loads.

The AD8024 outputs settle to 0.1% within 35 ns into a 300 pF

load (6 V swing). The AD8024 can run on both +5 V as well as

± 12 V rails. Slew rate on ± 12 V supplies is 2400 V/µs. DC

Characteristics are outstanding with typical 2 mV offset, and

3

µA maximum input bias current. High-speed disable pin

allows the AD8024 to be shut down when not in use. Low-power

operation is assured with the 4 mA/Amplifier supply current draw.

The high voltage drive capability, low settling time, high slew

rate, low offset, and high bandwidth make the AD8024 ideally

suited as an LCD column driver, a video line driver, and for

use in high-performance test equipment.

The AD8024 is available in a 16-lead SOIC package.
