This document introduces the features and characteristics of AD624 high precision low noise instrumentation amplifier, including input offset voltage drift, output offset voltage drift, CMRR, maximum nonlinearity, etc.
The AD624 is a high precision, low noise instrumentation amplifier designed primarily for use with low level transducers such as load cells, strain gauges, and pressure transducers. It offers outstanding noise performance, high gain accuracy, low gain temperature coefficient, and high linearity, making it ideal for high resolution data acquisition systems.
The device features pin programmable gains of 1, 100, 200, 500, and 1000, with additional gains achievable through external resistors. Key specifications include a gain bandwidth product of 25 MHz, a slew rate of 5 V/µs, and an input noise typically less than 4 nV/√Hz at 1 kHz.
| Gain Bandwidth Product | 25 MHz |
|---|---|
| Slew Rate | 5 V/µs |
| Input Noise (1 kHz) | < 4 nV/√Hz |
| Pin Programmable Gains | 1, 100, 200, 500, 1000 |
