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