GENERAL DESCRIPTION
power supply and with dual supplies from ± 5 V to ± 15 V. This The AD818 is a low cost video op amp optimized for use in power supply flexibility, coupled with a very low supply current video applications that require gains equal to or greater than +2 of 7.5 mA and excellent ac characteristics under all power sup- or –1. The AD818’s low differential gain and phase errors, ply conditions, make the AD818 the ideal choice for many single supply functionality, low power, and high output drive demanding yet power sensitive applications. make it ideal for cable driving applications such as video cameras and professional video equipment. The AD818 is a voltage feedback op amp and excels as a gain stage in high speed and video systems (gain ≥ 2, or gain £ –1). It With video specs like 0.1 dB flatness to 55 MHz and low differ- achieves a settling time of 45 ns to 0.1%, with a low input offset ential gain and phase errors of 0.01% and 0.05∞, along with voltage of 2 mV max. 50 mA of output current, the AD818 is an excellent choice for The AD818 is available in low cost, small 8-lead PDIP and SOIC packages.
