Description:

Microvolt/Milivolt High Precision Voltage Amplifier AD620 Amplifier Transmitter. This is a a High Precision Signal Amplifier Board/Voltage Amplifier Module based upon AD620 Instrumentation amplifier IC, Input voltage range: DC 3~12V, Amplification: adjustable 1.5~1000 times, Adjustable zero to improve accuracy. Can be used for AC, DC signal amplification.

: Wide input range - This product adopts AD620 to amplify and can amplify microvolts and millivolts. Compared withLM358 on the market , it has high amplification precision and good linearity. The maximum voltage output range is ±10V . 

: Magnification -  The potentiometer is used to amplify the input signal. The magnification is up to 1000 times and can be adjusted only by a potentiometer.  

3 : Adjustable zero point Adjust the zero point   by zeroing potentiometer, improve the accuracy, and there will be no zero drift phenomenon to meet customer needs.

4 : The negative pressure output  - This module uses 7660A negative voltage chip output negative pressure ( -Vin ), which can be supplied to customers to drive other dual power loads.  

 

Features:

  • The AD620 amplification, can amplify microvolt, millivolt, offers higher amplification precision than LM358, the max voltage output range is ± 10V.

  • It uses potentiometer to amplify the input signal, max amplification can be 1000 times, can be adjusted by the potentiometer.

  • It can not only improve the accuracy, but also can avoid the zero drift phenomenon by using the zero potentiometer to adjust the zero.

  • The module adopts 7660A negative voltage chip to output negative voltage(-Vin), can be used to drive other dual power load.

 

Specifications:

The positive selection based on the input supply voltage power supply input voltage of the anode

1).  13-24 v power supply voltage of 24 v port, at this time + E output 12 v voltage for power supply.

2).  When the power supply voltage is 5-13 v + E.

  • GND power supply cathode
  • + S signal input terminal
  • -s signal input negative side (can connect GND)
  • The OUT signal output
  • - E output a - 5 v voltage (for sensor power supply)

Note: The input signal, the output signal, power input, must be total to three signals.

3).  Magnification: 1-1000 multiples is smaller, the greater the bandwidth

4).  Signal input voltage: 100 uv - 300 mv

5).  Output voltage: positive pressure + 6.5 V or so, negative pressure - 4 V or so.

6).  Magnification adjust way: by board

7).  Adjust zero, + S and -s short connect, adjust the zero potentiometer output of 0v to improve precision of the module.
