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.
