PRODUCT DESCRIPTION
The AD8026 is a complete low cost, closed loop, voltage feed-
back, quad amplifier. Precision trimmed resistors set a fixed RF/
RG ratio of 5/3 to a typical gain accuracy of 0.02%. Manufac-
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.
