Ad620 Micro Voltage Signal Amplifier Module

Ad620 Micro Voltage Signal Amplifier Module

DC 12V Micro Small Voltage Measurement Board Instrumentation Amplifier Voltmeter Adjustable 1000x Gain

     AD620 is used for measuring signals at low voltage levels. It can amplify signals at micro volt uV and milli volt mV level. Measurement can be made with high precision. It can amplify between 1.5 and 1000 times. There are 2 potentiometers on the board for the gain and zero adjustment.

     There is a 7660 negative voltage generator IC on the board. It generates the negative supply needed in the circuit. This negative voltage is accessible from the sockets on the board. You can use it as a negative voltage source that may be needed in external circuits.
