Description

AD829JNZ The external compensation pin of the AD829JN gives it exceptional versatility. For example, compensation can be selected to optimize the bandwidth for a given load and power supply voltage. As a gain-of-2 line driver, the −3 dB bandwidth can be increased to 95 MHz at the expense of 1 dB of peaking. Its output can also be clamped at its external compensation pin. The AD829JN exhibits excellent dc performance. It offers a minimum open-loop gain of 30 V/mV into loads as low as 500Ω, a low input voltage noise of 1.7 nV/√Hz, and a low input offset voltage of 1 mV maximum. Common-mode rejection and power supply rejection ratios are both 120 dB. This op amp is also useful in multichannel, high speed data mconversion 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 speedDACs. CONNECTION DIAGRAM Figure 1. 8-Lead PDIP (N), CERDIP (Q), and SOIC (R) Figure 2. 20-Terminal LCC Operating as a traditional voltage feedback amplifier, the AD829JN provides many of the advantages that a transimpedance amplifier offer. A bandwidth >50 MHz can be maintained for a range of gains through the replacement of the external compensation capacitor. The AD829 and the transimpedance amplifier are both unity-gain stable and provide similar voltage noise performance (1.7 nV/√Hz); however, the current noise of the AD829JN(1.5 pA/√Hz) is less than 10% of the noise of transimpedance amplifiers. The inputs of the AD829 are symmetrical.
