Features:

• 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.

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

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

• 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.

• 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.

Parameters:

• Size: 32 * 22mm
  

• Signal input voltage: 100uV - 300mV

• Signal output range: ± (Vin-2V)

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

• magnification: 1.5-1000 times adjustable, zero adjustable

• Offset voltage: 50μV.

• Input bias current: 1.0nA (max).

• Common mode rejection ratio: 100 dB

• Offset voltage drift: 0.6μV / ℃ (maximum).

• Stability: 2μV / month maximum

• 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.
