-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.
-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.
-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.
SPECIFICATION:
-The positive selection based on the input supply voltage power supply input voltage of the anode
-13-24 v power supply voltage of 24 v port, at this time + E output 12 v voltage for power supply.
-When the power supply voltage is 5-13 v + E.
-Magnification: 1-1000 multiples is smaller, the greater the bandwidth
-Signal input voltage: 100 uv - 300 mv-
-Output voltage: positive pressure + 6.5 V or so, negative pressure - 4 V or so.
-Magnification adjust way: by board
-Adjust zero, + S and -s short connect, adjust the zero potentiometer output of 0v to improve precision of the module.
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.
