AD829

The AD829 is a low noise (1.7 nV/Hz), high speed op amp with custom compensation that provides the user with gains from ±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 band- width product while requiring only 5 mA of current from the power supplies.

The AD829's external compensation pin gives it exceptional versatility. For example, compensation can be selected to opti- mize the bandwidth for a given load and power supply voltage. As a gain-of-two line driver, the 3 dB bandwidth can be in- creased to 95 MHz at the expense of 1 dB of peaking. In addi- tion, the AD829's output can also be clamped at its external compensation pin.
