High -precision micro -volt/millivol voltage amplifier module small signal instrument AD620 transmitter

High -precision micro -volt voltage voltage amplifier small signal instrument AD620 transmitter

The AD620 is used as the main amplifier, which can enlarge slightly and the millivol voltage.The amplification multiple is 1.5-1000 times, which can be adjusted.High accuracy, low disorders and better linear.Adjustable zero and improve accuracy.Can be used for communication and DC models.

High -precision, low imbalance, communication, DC micro -voltage, millivolvoral voltage amplifier can be enlarged by small signals that can communicate and DC, and micro -volt and millivoli voltage is large.(The use of the module requires a certain electronic foundation. If there is no basic customers, please buy it with caution. Our store provides technical support.)

Product highlights:

1: The input range is widely enlarged by AD620, which can enlarge slightly and millivoltory, which is higher than the LM358 amplification accuracy and good linearity, and the large voltage output range is ± 9V.

2: The amplification multiple uses the potentiometer to enlarge the input signal, and the amplification multiple is as high as 1000 times. It only needs to be adjusted by a potentiometer.

3: The zero -point adjustment can be adjusted by adjusting the zero point to improve the accuracy, and there will be no zero -point drift to meet customer needs.

4: The negative pressure output module uses the 7660A negative pressure chip output negative pressure (-Vin), which can be provided to the customer to drive other dual power loads.

5: The MINI type size is 32*22mm, and the positioning hole of 4 3mm is evenly distributed evenly. The two sides are 2.54mm standard spacing.

Product parameters:

1. Input voltage: 3-11VDC.(Customized batch)

2. Magnification multiple: 1.5-1000 times can be adjusted, zero-point adjustment

3. Signal input voltage: 100UV--300MV

4. Signal output range: ± (vin-2V)

5. negative pressure output: greater than -Vin.Due to the problem of internal resistance of the negative pressure chip, the actual output is greater than -Vin. The greater the load power, the larger the negative pressure drop.

6. Disordable voltage: 50 μV.
7. Input bias current: 1.0NA (large value).

8. Common model suppression ratio: 100dB

9. Disordable voltage drift: 0.6 μV/° C (high value).
10. Stability, Time: 2 μV/MONTH

11. Module weight: 4G

12. Size: 32*22mm

How to use:

注意：+S :信号输入端，-S:信号输入负端（可接GND），Vout 信号输出，V-输出一个-Vin的电压（可供传感器供电）.信号输入，信号输出，电源输入，3 signals must be together.

1. The zero-wiring diagram is used to zero the wiring before the use of the figure, and the+s and -s are short. Adjust the zero-regulating knob to make the output VOUT 0V.
