KNACRO AD620 Millivolt/Microvolt Voltage Signal Amplifier Module Adjustable Magnification Instrumentation Amplifier Module Mini Voltage Amplifier Module

High-end dedicated instrumentation amplifier AD623 core, high precision, good linearity.
Single power supply, support 3-5.5V power supply, easy to use.
Integrated negative voltage generation module, dual power supply operation, easy to deal with negative signal/AC signal.
Power input LC filter, pure and stable, to ensure stable signal amplification.
Built-in negative voltage generation module, only a single power supply can achieve double power operation, simplified system design.
Rail-to-rail output, the maximum output swing is up to + -VCC, far beyond the LM358 core products.
Magnification 2-1000 times is adjustable with potentiometer, adapt to different applications.
Module is simple, scalable and easy to facilitate the secondary development.
