AD620 MICROVOLT/MILIVOLT HIGH PRECISION VOLTAGE AMPLIFIER 1000 TIMES GAIN

AD620 HIGH PRECISION VOLTAGE AMPLIFIER

AD620 High Precision Voltage 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.
