GENERAL DESCRIPTION The AD828 is fully specified for operation with a single 5 V The AD828 is a low cost, dual video op amp optimized for use power supply and with dual supplies from ±5 V to ±15 V. This in video applications that require gains of +2 or greater and power supply flexibility, coupled with a very low supply current high output drive capability, such as cable driving. Due to its of 15 m A and excellent ac characteristics under all power supply low power and single-supply functionality, along with excellent conditions, make the AD828 the ideal choice for many demand- differential gain and phase errors, the AD828 is ideal for power- ing yet power-sensitive applications. sensitive applications such as video cameras and professional
