Your affirmation is our greatest motivation ! ! !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.

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.
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: 50μV
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 x 21 x 11/1.18 x 0.83 x 0.43inch
