AD623 AC/DC High Precision Small Voltage Signal Amplifier Module
This device uses an AD623 as an amplifier that is capable of amplifying small voltage signal (e.g. µV) AC or DC. By adjusting the on-board potentiometer, the magnification can be adjusted to go as high as up to 1000 times. This module has a low voltage offset, great linearity, and also, an adjustable zero potentiometer to improve its accuracy.
- Application: Low Power Medical Instrumentation, Transducer Interface, Thermocouple Amplifier, Industrial Process Controls, Difference Amplifier, Low Power Data Acquisition.
- Advantages: High-end dedicated instrumentation amplifier AD623 core, high precision, good linearity
Easy to deal with: Integrated negative voltage generation module, dual power supply operation, easy to deal with negative signal/AC signal - Signal Stability: Power input LC filter, pure and stable, to ensure stable signal amplification
- Simplified Design: Built-in negative voltage generation module, only a single power supply can achieve double power operation, simplified system design
