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 mA 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 The AD828 is a voltage feedback op amp that excels as a gain video equipment. stage (gains > +2) or active filter in high speed and video systems With video specs like 0.1 dB flatness to 40 MHz and low and achieves a settling time of 45 ns to 0.1%, with a low input differential gain and phase errors of 0.01% and 0.05°, along offset voltage of 2 mV max. with 50 mA of output current per amplifier, the AD828 is an The AD828 is available in low cost, small 8-lead plastic mini-DIP excellent choice for any video application. The 130 MHz gain and SOIC packages. bandwidth and 450 V/µs slew rate make the AD828 useful in many high speed applications, including video monitors, CATV,
