AD620 High Precision DC 3-12V Microvolt / Millivolt Voltage Amplifier Module

AD620 DC 3-12V High Precision Microvolt/Millivolt Voltage Amplifier Module

Features:

• Using AD620 as the main amplifier can amplify μV and mV voltage
• Magnification 1.5-10000 magnification, adjustable
• High precision, low offset, better linearity
• Adjustable zero to improve accuracy
• Can be used for AC, and DC signal amplification

Product Highlights:

• High Accuracy Amplification: Wide supply voltage range, the AD620 amplification of this product can be amplified microvolts, millivolt, compared to LM358 amplification accuracy, better linearity, the maximum voltage output range of ± 10V
• Adjustable Magnification: Magnification range, magnification up to 1000 times, only through a potentiometer can be adjusted
• Zero Drift Free: Adjustable zero through the zero potentiometers to adjust the zero, and improve accuracy, there will be no zero drift phenomenon to meet customer needs
• Negative Voltage Output: With a negative voltage output, the module uses a 7660A chip output negative voltage (-Vin), which can be provided to the customer to drive another dual power load
• Compact Design: Mini type, the size of 32 * 22mm, evenly distributed around the four 3mm positioning holes, both sides of the port 2.54mm standard pitch pinhole

Product Parameters:

• Input voltage: 3-12VDC (Bulk purchase can be customized)
• Magnification: 1.5-1000 times adjustable, zero adjustable
• Signal input voltage: 100uV - 300mV
• Signal output range: ± (Vin-2V)
• Negative voltage output: higher than -Vin. As the negative voltage chip output resistance problem, the actual output is higher than -Vin, the greater the load power, the greater the negative voltage drop.
