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. Module use, need to have a certain electronic basis, if no basis customers, please carefully purchase, shop to provide technical support. Product Highlights: 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, 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. Offset voltage: 50μV. Input bias current: 1.0nA (max). Common mode rejection ratio: 100 dB Offset voltage drift: 0.6μV / ℃ (maximum). Stability: 2μV / month maximum Size: 32 * 22mm ProductSiteLaunchDate : 2021-06-26T18:41:11.981Z Size : AC-013 Male
