AD620 Microvolt MV Voltage Amplifier Signal Instrumentation Module DC 3-12V 1.5-1000 times Adjustable Microvolts Millivolts Board

Explanation:

Using AD620 as the main amplifier, it can amplify microvolt and millivolt voltage. The magnification is 1.5-10000 times, adjustable. High accuracy, low offset, and better linearity. Zero can be adjusted to improve accuracy. Can be used for AC and DC model amplification. High precision, low offset, AC, DC microvolt, millivolt voltage amplifier, can be used for AC, DC small signal amplification, microvolt, millivolt voltage amplification.

Features:

1. Amplification: The potentiometer is used to amplify the input signal, and the amplification is as high as 1000 times, which can be adjusted by only one potentiometer.

2. Mini type: The size is 32*22mm, four 3mm positioning holes are evenly distributed around, and the two sides are arranged with a standard spacing of 2.54mm.

3. Adjustable zero point: adjust the zero point through the zero adjustment potentiometer to improve the accuracy, and there will be no zero point drift phenomenon to meet customer needs.

4. With negative pressure output: The module adopts 7660A negative pressure chip to output negative pressure (-Vin), which can be provided to customers to drive other dual power loads.

5. Wide input range: This product uses AD620 amplification, which can amplify microvolts and millivolts. It has higher amplification accuracy and better linearity than LM358 on the market, and the maximum voltage output range is ±10V.

Specification:

Size: 32*22mm

Offset voltage: 50μV.

Input voltage: 3-12V DC

Signal output range: ±(Vin-2V)

Input bias current: 1.0nA (max)

Signal input voltage: 100uV--300mV

Common mode rejection ratio: 100dB

Stability time: 2μV/month maximum

Offset voltage drift: 0.6μV/℃ (maximum)

Magnification: 1.5-1000 times adjustable, zero point adjustable

Negative pressure output: greater than -Vin. Due to the problem of the output internal resistance of the negative pressure chip, the actual output is greater than -Vin, the greater the load power, the greater the negative pressure drop.
