This product is a High Precision Signal Amplifier Board/Voltage Amplifier Module based on the AD620 Instrumentation amplifier IC. It has an input voltage range of DC 3~12V and adjustable amplification from 1.5 to 1000 times. The module allows for amplification of both AC and DC signals.
The AD620 amplification feature enables the amplification of microvolts and millivolts with high precision and good linearity compared to the LM358. The maximum voltage output range is ±10V.
The potentiometer on the module is used to amplify the input signal, with a magnification of up to 1000 times. The zero-point can be adjusted using the zeroing potentiometer to enhance accuracy and prevent zero drift.
Additionally, the module utilizes a 7660A negative voltage chip to output negative pressure (-Vin), which can be used to drive other dual power loads.
