Description Description&Previewshipping&policyDescription:Using AD620 as the main amplifier, it can amplify microvolt and millivolt voltages. Magnification 1.5-10000 times, adjustable. High precision, low misalignment and better linearity. Adjustable zero to improve accuracy. Can be used for AC, DC model amplification. High precision, low imbalance, AC, DC microvolt, millivolt voltage amplifier, can be used for AC, DC small signal amplification, microvolt, millivolt voltage amplification. (The use of modules, you need to have a certain electronic basis, if there is no basic customer, please buy carefully, the shop provides technical support.) Product highlights: 1: Wide input range This product uses AD620 magnification, magnifying microvolt, millivolt, compared with LM358 on the market amplification accuracy is higher, better linearity, maximum voltage output range ±10V. 2: amplification using potentiometer to enlarge the input signal, amplification up to 1000 times, only need to be adjusted through a potentiometer. 3: Adjustable zero by adjusting the zero potentiometer, improve the accuracy, there will be no zero drift phenomenon, to meet customer needs. 4: The negative pressure output module adopts 7660A negative pressure chip to output negative pressure (-Vin), which can be provided to customers to drive other double power loads. 5: Mini size is 32*22mm, four 3mm positioning holes are evenly distributed around, and 2.54mm standard spacing is arranged on both sides. Product parameters: 1. Input voltage: 3-12VDC. (Batch can be customized) 2. Magnification: 1.5-1000 times adjustable, zero adjustable 3. Signal input voltage: 100uV--300mV 4. Signal output range: ± (Vin-2V) 5. Negative pressure output: greater than -Vin. Due to the internal resistance of the negative pressure chip output, the actual output is greater than -Vin, and the greater the load power, the greater the negative pressure drop. 6. Offset voltage: 50?V. 7. Input bias current: 1.0nA (maximum). 8. Common-mode rejection ratio: 100dB 9. Offset voltage drift: 0.6?V/? (maximum). 10. Stable, time: 2?V/month Max 11. Module weight: 4g 12. Size: 32*22mm The output signal distortion is small, high frequency, with noise filtering ability, more suitable for the size of the signal.
