ITEM NAME:AD620 uV mV Voltage Amplifier Small Signal Instrumentation Amplifier Board A#S Product Description Description: 3-12V DC High Precision AD620 Microvolt mV Voltage Amplifier Module Small Signal Instrumentation Amplifier Board Description: Using AD620 as the main amplifier, can amplify uV, mV voltage. Magnification 1.5-10000 magnification, adjustable. High precision, low offset, better linearity. Adjustable zero to improve accuracy. Can be used for AC, DC signal amplification. A certain electronic basis is required for this module use. Feature: 1. 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. 2. Magnification range: magnification up to 1000 ti2mes, only through a potentiometer can be adjusted. 3. Adjustable zero through the zero potentiometer to adjust the zero, improve accuracy, there will be no zero drift phenomenon to meet customer needs. 4. A negative voltage output: the module uses 7660A chip output negative voltage (-Vin), can be provided to the customer to drive other dual power load. 5. Mini type: evenly distributed around the four 3mm positioning holes, both sides of the port 2.54mm standard pitch pinhole. Specification: Input voltage: 3-12V DC 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 Offset voltage: 50ÃŽ ¼V Input bias current: 1.0nA (max). Common mode rejection ratio: 100 dB Offset voltage drift: 0.6uV / ℃ (maximum) Stability: 2uV / month maximum Product size: 30*21*11/1.18*0.83*0.43" Note: 1. There may be slight size deviations due to manual measurement, different measuring methods and tools. 2. The picture .Magnification 1.5-10000 magnification, adjustable. High precision, low offset, better linearity. Adjustable zero to improve accuracy. Can be used for AC, DC signal amplification. A certain electronic basis is required for this module use.
