GENERAL DESCRIPTION

The AD829 is a low noise (1.7 nV/√Hz), high speed op amp with custom compensation that provides the user with gains of ±1 to ±20 while maintaining a bandwidth greater than 50 MHz. The AD829’s 0.04° differential phase and 0.02 differential gain performance at 3.58 MHz and 4.43 MHz, driving reverse terminated 50 Ω or 75 Ω cables, makes it ideally suited for professional video applications. The AD829 achieves its 230 V/µs uncompensated slew rate and 750 MHz gain bandwidth while requiring only 5 mA of current from power supplies.
