AD620 Transmitter High Precision Microvolt Millivolt Voltage Amplifier Small Signal Instrumentation AmplifierItem NO.: AD620

AD620 Transmitter

Product Information:

Using AD620 as the main amplifier, it can amplify microvolt and millivolt voltage. The magnification is 1.5-10000 times, adjustable. High accuracy, low offset, and better linearity. Zero can be adjusted to improve accuracy. Can be used for AC and DC model amplification.

High precision, low offset, AC, DC microvolt, millivolt voltage amplifier, can be used for AC, DC small signal amplification, microvolt, millivolt voltage amplification. (The use of the module requires a certain electronic foundation. If there is no basic customer, please purchase it carefully, and our store provides technical support.)

Product Highlights:

1: Wide input range This product uses AD620 amplification, which can amplify microvolts and millivolts. It has higher amplification accuracy and better linearity than LM358 on the market, and the maximum voltage output range is ±10V.

2: Magnification The potentiometer is used to amplify the input signal, and the magnification is as high as 1000 times, which can be adjusted by only one potentiometer.

3: Adjustable zero point The zero point is adjusted by the zero adjustment potentiometer to improve the accuracy, and there will be no zero point drift phenomenon to meet customer needs.

4: With negative pressure output The 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 type The size is 32*22mm, four 3mm positioning holes are evenly distributed around, and the two sides are arranged with a standard spacing of 2.54mm.

Product Parameters:

1. Input voltage: 3-12VDC. (Batch can be customized)

2. Magnification: 1.5-1000 times adjustable, zero point adjustable

3. Signal input voltage: 100uV--300mV

4. Signal output range: ±(Vin-2V)

5. Negative pressure output: greater than -Vin. Due to the problem of 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.

6. Offset voltage: 50μV.

7. Input Bias Current: 1.0nA (max).

8. Common mode rejection ratio: 100dB

9. Offset voltage drift: 0.6μV/°C (max).

10. Stable, time: 2μV/month max

11. Module weight: 4g

12. Size: 32*22mm
