Its 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 unpensated slew rate and 750 MHz gain bandwidth while requiring only 5 m A of current from power supplies. The external pensation pin of the AD829 gives it exceptional versatility. For example, pensation can be selected to optimize the bandwidth for a given load and power supply voltage. As a gain-of-2 line driver, the - 3 d B bandwidth can be increased to 95 MHz at the expense of 1 d B of peaking. Its output can also be clamped at its external pensation pin. The AD829 exhibits excellent dc performance. It offers a minimum open-loop gain of 30 V/m V into loads as low as 500 Ω, a low input voltage noise of 1.7 n V/√Hz, and a low input offset voltage of 1 m V maximum. mon-mode rejection and power supply rejection ratios are both 120 d B. This op amp is also useful in multichannel, high speed data conversion where its fast (90 ns to 0.1%) settling time is important. In such applications, the AD829 serves as an input buffer for 8-bit to 10-bit ADCs and as an output I/V converter for high speed DACs. Rev....
