The AD828 is a low-cost, dual video op amp optimized for use in video applications that require gains of +2 or greater and high output drive capability, such as cable driving.
The AD828 is a low‑cost, dual video operational amplifier optimized for video applications that require gains of +2 or greater and high output‑drive capability. It operates from single‑supply (+5 V) or dual‑supply (+5 V to +15 V) configurations, drawing only 15 mA supply current while delivering up to 50 mA per amplifier.
The datasheet provides extensive performance data, including a 130 MHz 3 dB bandwidth at a gain of +2, 450 V/µs slew rate, 2 mV input offset voltage, and excellent differential gain and phase errors (0.01 %). Typical application circuits such as video line drivers and low‑distortion amplifiers are illustrated, along with detailed pin‑outs and package dimensions.
