Description
The AD823 is a dual precision, JFET-input operational amplifier designed for high-performance signal processing. It features true single-supply capability, with an input voltage range that extends below ground, and supports a wide supply range from 3V to 36V (or ±1.5V to ±18V). Engineered for versatility, this amplifier excels at driving heavy capacitive loads up to 500pF and provides a 15mA output current. Its combination of high-speed AC performance and excellent DC precision makes it a premier choice for demanding data acquisition and instrumentation systems.
Key Features
- Rail-to-Rail Performance: Output swings rail-to-rail, with an input voltage range that extends below ground in single-supply mode.
- High Speed: 16MHz Gain Bandwidth Product (GBP) and a 22V/µs slew rate for rapid signal response.
- Fast Settling: 320ns settling time to 0.1% accuracy, ideal for high-resolution data systems.
- Precision Input: Low input offset voltage (0.2mV typ) and low bias current (3pA typ) with no phase inversion.
- Low Distortion: Excellent harmonic distortion performance (-108dBc typ) and low input voltage noise (16nV/√Hz).
- High Load Drive: Stable while driving up to 500pF of direct capacitive load as a follower.
Applications
- Data Acquisition: Ideal for 12-bit to 16-bit A/D driver and data acquisition systems.
- Precision Instrumentation: Suited for battery-powered instruments, medical monitoring equipment, and photodiode preamps.
- Filtering: High-speed active filters and signal conditioning chains.
- General Electronics: Versatile enough for a wide range of low-voltage, high-dynamic-range applications.
