PRODUCT DESCRIPTION

The AD8026 is a complete low cost, closed loop, voltage feed-

tured on ADI’s proprietary XFCB high speed bipolar process,

which enables the output drivers to settle to within 0.1% within

55 ns into a 100 pF load (4 V swing) and drive output voltages

to rated settling time to within 0.5 V from the rail. The typical

3 dB bandwidth is 60 MHz, at G = +2.67. The AD8026 is

laser trimmed to produce both exceptional offset and gain

performance.

The low settling time, high slew rate, low offset and rail-to-rail

output voltage drive capability makes the AD8026 ideal for

driving LCD displays.

The AD8026 is available in a 14-lead SOIC package.
