3-12VDC AD620 Microvolt MV Voltage Amplifier Signal Instrumentation Module Board

Amplifier Signal Microvolt / Millivolt Voltage Module AD620


QUICK SPECS:

Input Voltage: DC 3-12V
Amplification Times:1.5-1000 times adjustable, zero point adjustable
Signal Input Voltage:100uV-300mV
Signal Output Range:+/-(Vin-2V)
Negative Voltage Output: more than Vin. Because of the negative voltage chip output internal resistance, the actual output is more than Vin.The higher of the load power is, the larger of the negative voltage will be
Offset Voltage:50uV
Input Bias Current:1.0nA (max)
Common Mode Rejection Ratio:100dB
Offset Voltage Drift:0.6uV/celsius
Stable Time:2uV/month (max)
Size:32*22mm

FEATURES:

Wide Input Range: adopt AD620 amplification, and the max voltage output range is +/-10V
Amplification Times: adopt potentiometer for amplifying input signals, and the amplification times can be up to 1000 times
Adjustable Zero Point: use zero potentiometer to adjust the zero point;if improves the precision, it won't lead to zero point drifting
Negative Voltage Output: adopt 7660A negative voltage chip output negative voltage (-Vin)
Smallest Size: 32*22mm,and the pitch is 2.54mm
