This is a High Precision Signal Amplifier Board/Voltage Amplifier Module based upon AD620 Instrumentation amplifier IC, Input voltage range: DC 3~12V, the amplification is adjustable to 1.5~1000 times, Adjustable zero to improve accuracy. AD620 Instrumentation Voltage Amplifier Module is used for AC, DC signal amplification. If you give the input in MicroVolt the output will be amplified to ± 10 V. The gain and amplification can be controlled onboard.
Wide input range – This product adopts AD620 to amplify, the AD620 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.
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.
Adjustable zero-point – Adjust the zero point by zeroing the potentiometer, improve the accuracy, and there will be no zero drift phenomenon to meet your needs.
The negative pressure output – This module uses 7660A negative voltage chip output negative pressure( -Vin)
