**AD829JNZ: High-Performance, 80 MHz JFET-Input Operational Amplifier**

In the realm of precision analog electronics, the selection of an operational amplifier is critical to achieving desired system performance. The **AD829JNZ** stands out as a high-performance, monolithic op-amp engineered to excel in demanding applications. This device combines a **high-speed JFET-input stage** with a bipolar output stage, delivering a remarkable **80 MHz gain bandwidth product** and a fast **150 V/µs slew rate**. These characteristics make it an exceptional choice for circuits requiring wide bandwidth and rapid signal processing.

A key advantage of the AD829JNZ is its **JFET-input architecture**, which provides an ultra-high input impedance, typically greater than 10^12 Ω. This feature minimizes the loading effect on previous stages, making it ideal for buffering high-impedance sources, such as photodiodes, and for use in active filters and precision integrators. Furthermore, the low input bias current ensures that errors in sensitive measurement applications are significantly reduced.

The amplifier is also designed for stability and versatility. It is **compensated for unity-gain stability**, allowing it to operate reliably in all negative feedback configurations without external components. Its output stage is capable of driving loads as low as 500 Ω to within 10 V of the supply rails, providing substantial output current for a wide range of applications. These include professional video equipment, high-speed data acquisition systems, pulse amplifiers, and medical instrumentation.

Housed in a robust 8-pin PDIP package, the AD829JNZ is built for reliability across industrial temperature ranges. Its combination of speed, precision, and drive strength establishes it as a superior component for designers seeking to enhance signal fidelity and system bandwidth.

**ICGOOODFIND:** The AD829JNZ is a quintessential high-speed JFET-input op-amp, offering an optimal blend of wide bandwidth, fast slew rate, and high input impedance, making it a robust solution for professional video, instrumentation, and data acquisition systems.
