GENERAL DESCRIPTION
The AD828 is a low cost, dual video op amp optimized for use
in video applications that require gains of +2 or greater and
high output drive capability, such as cable driving. Due to its
low power and single-supply functionality, along with excellent
differential gain and phase errors, the AD828 is ideal for power-
sensitive applications such as video cameras and professional
video equipment.
With video specs like 0.1 dB flatness to 40 MHz and low
differential gain and phase errors of 0.01% and 0.05°, along
with 50 mA of output current per amplifier, the AD828 is an
excellent choice for any video application. The 130 MHz gain
bandwidth and 450 V/µs slew rate make the AD828 useful in
many high speed applications, including video monitors, CATV,
color copiers, image scanners, and fax machines.

The AD828 is fully specified for operation with a single 5 V
power supply and with dual supplies from ± 5 V to ± 15 V. This
power supply flexibility, coupled with a very low supply current
of 15 mA and excellent ac characteristics under all power supply
conditions, make the AD828 the ideal choice for many demand-
ing yet power-sensitive applications.
The AD828 is a voltage feedback op amp that excels as a gain
stage (gains > +2) or active filter in high speed and video systems
and achieves a settling time of 45 ns to 0.1%, with a low input
offset voltage of 2 mV max.
The AD828 is available in low cost, small 8-lead plastic mini-DIP
and SOIC packages.
