8. PCB Layout Guide
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:
T1: Local Temperature. T2: External Temperature 1. T3:External Temperature 2
The value in quota is its power-on default value.
PCB can be electrically noisy environments, and the F75386 is measuring very small voltage from the
