ماژول تقویت کننده سیگنال ابزاردقیق تفاضلی دارای چیپ AD620 و بهره قابل تنظیم
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);
