*1: Input logic circuit to determine the
specified measuring conditions.
Note:
- Please have the shortest layout for the common node (wiring patterns which are connected to the external capacitors, resistors
and IN0/IN1 pin), including CVR0/CVR1. Especially, do not have long wire between IN0/IN1 and RS0/RS1. The coupling
capacitance on the wires may occur incorrect A/D conversion. Also, please do not have signals which may be a source of noise
around the node.
- When RT0/RT1 (Thermistor and etc.) requires long wiring due to the restricted placement, please have VSS(GND) trace next to
the signal.
- Please make wiring to components (capacitor, resisteor and etc.) necessory for objective measurement. Wiring to reserved
components may affect to the A/D conversion operation by noise the components itself may have.
