Description:
This device uses an AD620 as an amplifier that is capable of amplifying small voltage signal (e.g. µV) AC or DC. By adjusting the on-board potentiometer, the magnification can be adjusted to go as high as up to 1000 times. This module has a low voltage offset, great linearity, and also, an adjustable zero potentiometer to improve its accuracy.

Features:
1. Input voltage: 3-12VDC. (Batch can be customized)
2. Magnification: 1.5-1000 times adjustable, zero adjustable
3. Signal input voltage: 100uV--300mV( DC/AC )
4. Signal output range: ± (Vin - 2V)
5. Negative pressure output: greater than -Vin. Due to the problem of internal resistance of the negative voltage chip output, the actual output is greater than -Vin, and the larger the load power, the larger the negative pressure drop.
6. Offset voltage: 50μV. 
7. Input bias current: 1.0nA (maximum).
8. Common mode rejection ratio: 100dB 
9. Offset voltage drift: 0.6μV/°C (maximum). 
10. Stable, time: 2μV/month maximum
11. Module weight: 4g
12. Size: 32*22mm

Pinout:
+S:signal input port;
-S:signal input negative port (can connect with GND);
Vout:signal output;
V-:output -Vin voltage (can supply power ofn sensors);

Note:
signal input,signal output,power input should be common ground

Package Include:
1x Amplifier Module
