High precision Microvolt/Millivolt voltage amplifier Small Signal instrumentation amplifier AD620 transmitter

High precision, low imbalance, AC, DC microvolt, millivolt voltage amplifier, can be used for AC, DC small signal amplification, microvolt, millivolt voltage amplification. (The use of the module, you need to have a certain electronic foundation, if there is no basic customer, please buy carefully, the store provides technical support.)
Product highlights:
1: Wide input range This product uses AD620 amplification, can amplify microvolt, millivolt, than the market LM358 amplification accuracy is high, good linearity, the maximum voltage output range of ±10V.
2: Amplification using potentiometer to amplify the input signal, amplification up to 1000 times, only need to be adjusted through a potentiometer.
3: Adjustable zero by adjusting the zero potentiometer, improve the accuracy, there will be no zero drift phenomenon, to meet customer needs.
4: The negative pressure output module adopts 7660A negative pressure chip to output negative pressure (-Vin), which can be provided to customers to drive other dual power loads.
5: Mini size is 32*22mm, four 3mm positioning holes are evenly distributed around, and the two sides are lined up with 2.54mm standard spacing.
Product parameters:
1. Input voltage: 3-12VDC. (Batch can be customized)
2. Magnification: 1.5-1000 times adjustable, zero adjustable
3. Signal input voltage: 100uV–300mV
4. Signal output range: ± (Vin-2V)
5. Negative pressure output: greater than -Vin. Due to the internal resistance of the output of the negative pressure chip, the actual output is greater than -Vin, and the greater the load power, the greater the negative pressure drop.
6. Offset voltage: 50μV.
7. Input bias current: 1.0nA (maximum value).
8. Common mode rejection ratio: 100dB
9. Offset voltage drift: 0.6μV/℃ (maximum value).
10. Steady, time: 2μV/ Monthmax
11. Module weight: 4g
12. Size: 32*22mm

How to use:
Note: +S: signal input, -S: signal input negative (GND can be connected), Vout signal output, V- output a -VIN voltage (for sensor power supply). Signal input, signal output, power input, 3 signals must be shared.

1.Before using the wiring diagram, adjust the wiring according to the diagram to zero, short-connect +S and -S, adjust the zero knob to make the output Vout 0V.

2.Single-ended input wiring diagram This wiring diagram applies to the single-ended output signals, sensors, and silicon photovoltaic cells.

3.Differential input wiring diagram This wiring diagram is suitable for differential output pressure sensors, Bridges and other sensors.
