AD829JN

Product Summary

The AD829 is a low noise , 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 50Ωor 75Ω 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.; The AD829 has excellent dc performance. It offers a minimum; open-loop gain of 30 V/mV into loads as low as 500Ω, low; input voltage noise , and a low input offset volt-age of 1 mV maximum. Common-mode rejection and power supply rejection ratios are both 120 dB.The AD829 is also useful in multichannel, high speed data;conversion where its fast (90 ns to 0.1%) settling time is of; importance. In such applications, the AD829 serves as an input; buffer for 8-to-10-bit A/D converters and as an output I/V con-; verter for high speed D/A converters.
