AD620 Instrumentation Module

AD620 Microvolt MV/ mV Voltage Amplifier Signal Instrumentation Module Board

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.

Specifications

• Input voltage range : DC 3~12V

• Amplification : adjustable 1.5~1000 times, adjustable zero

• Signal input voltage range : 100µV~300mV

• Signal output range : ± (Vin-2V)

• Negative voltage output : > -Vin, for the output resistance of negative voltage chip, the actual output is greater than -Vin, the greater the load power, the greater the negative voltage drop.

• Offset voltage : 50µV

• Input bias current : 1.0nA (Max)

• Common mode rejection ratio : 100dB

• Offset voltage drift : 0.6µV/? (Max)

• Dimension : 32x22mm

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.
