This is a High Precision Signal Amplifier Board/Voltage Amplifier Module based upon AD620 Instrumentation amplifier IC, Input voltage range: DC 3~12V, Amplification: adjustable 1.5~1000 times, Adjustable zero to improve accuracy. Can be used for AC, DC signal amplification.
1: Wide input range - This product adopts AD620 to amplify and can amplify microvolts and millivolts. Compared withLM358 on the market, it has high amplification precision and good linearity. The maximum voltage output range is ±10V.
2: Magnification - The potentiometer is used to amplify the input signal. The magnification is up to 1000 times and can be adjusted only by a potentiometer.
3: Adjustable zero-point - Adjust the zero point by zeroing potentiometer, improve the accuracy, and there will be no zero drift phenomenon to meet customer needs.
4: The negative pressure output - This module uses 7660A negative voltage chip output negative pressure ( -Vin ), which can be supplied to customers to drive other dual power loads.
