AD620 Microvolt MV Voltage Amplifier Signal Instrumentation Module Board DC3-12V

Using AD620 as the main amplifier, can amplify uV, mV voltage. Magnification 1.5-10000 magnification, adjustable. High precision, lowoffset, better linearity. Adjustable zero to improve accuracy. Can be used for AC, DC signal amplification.

1. Wide supply voltage range, the AD620 amplification of this product can be amplified microvolts, millivolt, compared to LM358 amplification accuracy, better linearity, the maximum voltage output range of ± 10V.

2. magnification range, magnification up to 1000 ti2mes, only through a potentiometer can be adjusted.

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

4. A negative voltage output, the module uses 7660A chip output negative voltage (-Vin), can be provided to the customer to drive other dual power load.

5. Mini type, the size of 32 * 22mm, evenly distributed around the four 3mm positioning holes, both sides of the port 2.54mm standard pitch pinhole.

Input voltage: 3-12VDC. (Bulk purchase can be customized)

magnification: 1.5-1000 times adjustable, zero adjustable

Signal input voltage: 100uV - 300mV

Signal output range: ± (Vin-2V)

Negative voltage output: higher than -Vin. As the negative voltage chip output resistance problem, the actual output is higher than -Vin, the greater the load power, the greater the negative voltage drop.

0ffset voltage: 50μV.

Input bias current: 1.0nA (max).

Common mode rejection ratio: 100 dB

0ffset voltage drift: 0.6μV / ° (maximum).

Stability: 2μV / month maximum

Size: 32 * 22mm

Weight: 4g
