AD620 Microvolt/Millivolt Voltage Amplifier Module

This AD620 Microvolt/Millivolt Voltage Amplifier Module is designed as a High Precision Signal Amplifier Board/Voltage Amplifier Module. These modules are based upon AD620 Instrumentation amplifier IC. It offers a wide Input voltage range of DC 3~12V. And at an Amplification rate of adjustable 1.5~1000 times. And also it offers Adjustable zero to improve accuracy. It is used for AC, DC signal amplification.

• Wide input range:  This IC adopts AD620 used to amplify microvolts and millivolts. Compared with LM358 on the market, it provides high amplification precision and good linearity. The maximum voltage output range ±10V.
• Magnification: The potentiometer is used to amplify the input signal. The magnification is up to 1000 times and adjusted via a potentiometer.
• Adjustable zero-point: Adjust the zero point by zeroing the potentiometer, improve the accuracy, and there will be no zero drift phenomenon to satisfy customer requirements.
• The negative pressure output: This module employs 7660A negative voltage chip output negative pressure ( -Vin ), which is supplied to customers to drive other dual power loads.

A voltage amplifier is defined as any circuit that puts out a better voltage than the input voltage. When we are true of a group amount of voltage, these amplifiers are widely used to increase the voltage. And thus the amount of power initiating of a circuit. This is often useful for reading and adapting small signals like boosting an audio signal before sending it on its thanks to speakers. The voltage amplifier may be a sort of the common emitter amplifier, which relies on the transistor. Also, the amplification of voltage depends on the ratio of resistors on the collector and emitter of this transistor.
