AD620 Microvolt/Millivolts Voltage Amplifier Signal Instrumentation Module Board

4Pcs AD620 Microvolt/Millivolts Voltage Amplifier Signal Instrumentation Module Board

Description:

Using AD620 as the main amplifier, can amplify microvolt/millivolts 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. (Module use, need to have a certain electronic basis, if no basis customers, please carefully purchase.)

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 times, 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: 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. magnification: 1.5-1000 times adjustable, zero adjustable Signal input voltage: 100μV - 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

Package Includes: 4* Voltage Amplifier Transmitter
