The high-precision long-range temperature measurement circuit composed of the ISO120 and XTR101 is mainly used in remote temperature measurement, temperature measurement accuracy is high and in the strong noise of the measurements. The ISO120 is the duty factor modulation / demodulation techniques designed a novel isolation amplifier. Isolation layerhas 2 matching lpF differential capacitors, the transmission is digital signal. The digital signal transmission will not affect the signal characteristics of isolated components of integrity. It also has good high frequency transient performance. The figure shows the high-precision long-range temperature measurement circuit composed of the ISO120 and XTR101.
