8. PCB Layout Guide
PCB can be electrically noisy environments, and the F75386 is measuring very small voltage from the
remote sensor, so care must be taken to minimize noise which is occurred at the sensor inputs. The
following guideline should be taken to reduce the measurement error of the temperature sensors:
