AD620 Microvolt/Millivolt Voltage Amplifier Module

Description:- 

This is a High Precision Signal Amplifier Board/Voltage Amplifier Module based upon AD620 Instrumentation amplifier IC.

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 a 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 potentiometers to adjust the zero.
• The module adopts a 7660A negative voltage chip to output negative voltage(-Vin), which can be used to drive other dual power loads
