Microvolt Mv Voltage Amplifier Signal Instrumentation Module Board 3-12V Dc, Product Details High Precision uV / mV Voltage Amplifier Small Signal Instrumentation Amplifier AD620 Transmitter - 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. (The use of the module requires a certain electronic foundation. If there is no basic customer, please buy with caution). - Mini type, the size is 32*22mm, 4 pieces of 3mm are evenly distributed around the positioning holes are arranged at 2.54mm standard spacing on both sides. 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: 50?V. - Input bias current: 1.0nA (max). - Common mode rejection ratio: 100 dB - Offset voltage drift: 0.6?V / (maximum). - Stability: 2?V / month maximum - Size: 32 * 22mm - Weight: 4g Package Included: 2* Voltage Amplifier Transmitter 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. (The use of the module requires a certain electronic foundation. If there is no basic customer, please buy with caution) Amplification the potentiometer is used to amplify the input signal, and the amplification is up to 1000 times, only need to pass a potentiometer to adjust. Adjustable zero point adjust the zero point through the zero-adjusting potentiometer to improve the accuracy. The phenomenon of zero drift appears to meet customer needs. There is negative pressure output the module adopts 7660A negative pressure chip to output negative pressure(-Vin), can be provided to customers to drive other dual power loads. Wide input range this product adopts AD620 amplification, which can amplify microvolts, milivolt, which has higher magnification accuracy, better linearity, and maximum power than the LM358 on the market voltage output range 9V.
