PRODUCT DESCRIPTION
The AD826 is a dual, high speed voltage feedback op amp. It
is ideal for use in applications which require unity gain stability
and high output drive capability, such as buffering and cable
driving. The 50 MHz bandwidth and 350 V/µs slew rate make
the AD826 useful in many high speed applications including:
video, CATV, copiers, LCDs, image scanners and fax machines.

The AD826 features high output current drive capability of
50 mA min per amp, and is able to drive unlimited capacitive
loads. With a low power supply current of 15 mA max for both
amplifiers, the AD826 is a true general purpose operational
amplifier.
The AD826 is ideal for power sensitive applications such as video
cameras and portable instrumentation. The AD826 can operate
from a single +5 V supply, while still achieving 25 MHz of band-
width. Furthermore the AD826 is fully specified from a single
+5 V to ± 15 V power supplies.
The AD826 excels as an ADC/DAC buffer or active filter in
data acquisition systems and achieves a settling time of 70 ns
to 0.01%, with a low input offset voltage of 2 mV max. The
AD826 is available in small 8-lead plastic mini-DIP and SO
packages.
