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.
