The AD828 is a low cost, dual video op amp optimized for use in video applications which require gains of +2 or greater and high ouput 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 demanding yet power sensitive applications.
The AD828 is a voltage feedback op amp which excels as a gain stage (gains>+2) or active filter and high speed 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-pin plastic mini-DIP and SOIC packages.

Tools & Simulations
AD828 SPICE Macro Models
Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.
Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.
A utility to convert between standard units of power measurement and signal strength.
This tool estimates die temperature and power dissipation based on the supply voltages, ambient temperature, load characteristics, and package thermal data.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability.
