GENERAL DESCRIPTION

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 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.

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.

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 available in low cost, small 8-lead plastic mini-DIP

and SOIC packages.
