AD620 instrument forstærker modul

Input voltage: 3-12VDC. 
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
Weight: 4g
