Millivolt Voltage Amplifier Module Point Microvolt

Kiss, you have a chance to meet, welcome you to our store, the store has a wide variety of products, home-based, see the heart of the goods can act, there is a baby you can also consult us, like we can point Bright stars.
1. The input range is wide. This product uses AD620 to amplify, which can amplify microvolts and millivolts. Possess higher amplification accuracy and better linearity than the LM358 on the market, and the maximum voltage output range is ±9V
2. A potentiometer is used to amplify the input signal, the magnification is up to 1000 times, and can be adjusted only through a potentiometer
3. The zero point can be adjusted by the zeroadjusting potentiometer to improve the accuracy, and there will be no zeropoint drift to meet customer needs
4. The module uses 7660A negative pressure chip to output negative pressure (-Vin), which can be provided to customers to drive other dual power loads
5. Mini type, size is 32 x 22mm, there are 4 3mm positioning holes evenly distributed around, 2.54mm standard spacing on both sides

Specification:
Item Type: Voltage Amplifier Module
Material: Resin
Model: AD620
Input Voltage: DC 3-11V
Magnification: 1.5-1000 Times adjustable, zero point adjustable
Common Mode Rejection Ratio: 100dB
Input Bias Current: 1.0nA (maximum)
Negative Pressure Output: Greater than -Vin. Due to the output internal resistance of the negative pressure chip, the actual output is greater than -Vin, and the greater the load power, the greater the negative pressure drop
Size: Approx. 32 x 22mm / 1.3 x 0.9in
Positioning Holes: Approx. 3mm / 0.12in
Standard Spacing: Approx. 2.54mm / 0.1in

How to Use:
Wiring diagram of zero adjustment before use, wire the zero adjustment according to the diagram, shortcircuit +S and S, and adjust the zero adjustment knob to make the output Vout 0V.

Package List:
1 x Voltage Amplifier Module
2 x Pin Header

Note:
+S: Signal input terminal, S: Signal input negative terminal(can be connected to GND), Vout signal output, V output a voltage of Vin (for sensor power supply). Signal input, signal output, power input, the 3 signals must share the ground.
