Product Details
The AD818 is a low cost, video op amp optimized for use in video applications which require gains equal to or greater than +2 or -1. The AD818 low differential gain and phase errors, single supply functionality, low power and high output drive make it ideal for cable driving applications such as video cameras and professional video equipment.
With video specs like 0.1 dB flatness to 55 MHz and low differential gain and phase errors of 0.01% and 0.05°, along with 50 mA of output current, the AD818 is an excellent choice for any video application. The 130 MHz 3 dB bandwidth (G= +2) and 500 V/µs slew rate make the AD818 useful in many high speed applications including: video monitors, CATV, color copiers, image scanners and fax machines.

Design Tools
Analog Filter Wizard
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.
Analog Photodiode Wizard
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.
VRMS/dBm/dBu/dBV calculators
A utility to convert between standard units of power measurement and signal strength.
Power Dissipation vs Die Temp
This tool estimates die temperature and power dissipation based on the supply voltages, ambient temperature, load characteristics, and package thermal data.
