1: this product is enlarged by AD620, which can be magnified and millivolt, which is higher than the market, which is high and linear, and the maximum voltage output range is plus or minus 10V.
2: the magnification USES a potentiometer to magnify the input signal, and the magnification is as high as 1000 times, but only by a potentiometer.
3: The zero point can be adjusted by the zero zero potentiometer, and the zero drift phenomenon will not be shown to meet the customer’s demand.
4: the negative pressure output module USES 7660A negative pressure chip output negative pressure (-vin), which can be used to drive other dual-power loads.
5: the Mini size is 32 * 22mm, and 4 3mm position holes are evenly distributed, the two sides are separated by 2.54 mm standard spacing.
Input voltage: 3-12V DC.
Magnification: 1.5-1000 times adjustable, zero point adjustable
Signal input voltage: 100uV – 300mV
Range of signal output: ± (Vin -2v)
Negative pressure output: greater than – Vin.
Due to the problem of the output of the negative pressure chip, the actual output is greater than -vin, and the greater the load power, the greater the negative pressure drop.
Imbalance voltage: 50 mu V.
Input bias current: 1.0nA (maximum).
Common mode inhibition ratio: 100dB
Offset voltage drift: 0.6 u V / ° (maximum).
Stability, time: 2 mu V/month maximum
1 x Signal Amplifier
