High Precision uV / mV Voltage Amplifier Small Signal Instrumentation Amplifier AD620 Transmitter

Using AD620 as the main amplifier, can amplify uV, mV voltage. Magnification 1.5-10000 magnification, adjustable. High precision, low offset, better linearity. Adjustable zero to improve accuracy. Can be used for AC, DC signal amplification. Module use, need to have a certain electronic basis, if no basis customers, please carefully purchase, shop to provide technical support.

Product Highlights:

1: wide supply voltage range, the AD620 amplification of this product can be amplified microvolts, millivolt, compared to LM358 amplification accuracy, better linearity, the maximum voltage output range of ± 10V.

2: magnification range, magnification up to 1000 ti2mes, only through a potentiometer can be adjusted.

3: adjustable zero through the zero potentiometer to adjust the zero, improve accuracy, there will be no zero drift phenomenon to meet customer needs.

4: a negative voltage output, the module uses 7660A chip output negative voltage (-Vin), can be provided to the customer to drive other dual power load.

5: mini type, the size of 32 * 22mm, evenly distributed around the four 3mm positioning holes, both sides of the port 2.54mm standard pitch pinhole.

Product parameters:

  1. Input voltage: 3-12VDC. (Bulk purchase 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 voltage output: higher than -Vin. As the negative voltage chip output resistance problem, the actual output is higher than -Vin, the greater the load power, the greater the negative voltage drop.
  6. Offset voltage: 50μV.
  7. Input bias current: 1.0nA (max).
  8. Common mode rejection ratio: 100 dB
  9. Offset voltage drift: 0.6μV / ℃ (maximum).
  10. Stability: 2μV / month maximum
  11. Size: 32 * 22mm
  12. Weight: 4g
Package Includes:
1* Voltage Amplifier Transmitter
