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. The AD818 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 7.5 mA and excellent ac characteristics under all power supply conditions, make the AD818 the ideal choice for many demanding yet power sensitive applications. The AD818 is a voltage feedback op amp and excels as a gain stage in high speed and video systems (gain = >2 or ­1). It achieves a settling time of 45 ns to 0.1%, with a low input offset voltage of 2 mV max. The AD818 is available in low cost, small 8-lead plastic miniDIP and SOIC packages.

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.

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 volts, which readily accumulate on the human body and on test equipment, can discharge without detection. Although the AD818 features proprietary ESD protection circuitry, permanent damage may still occur on these devices if they are subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid any performance degradation or loss of functionality.
