Use laminated ceramic capacitors (capacitance tolerance: ±10%, temperature coefficient: ±15%) or those
having higher characteristics.
Reference Voltage Pins for ADC
VREFP, VREFN, VREF0 (Output)
These pins are for generating a reference voltage inside Analog Front End. Connect a capacitor externally.

Use laminated ceramic capacitors (capacitance tolerance: ±10%, temperature coefficient: ±15%) or those
of higher characteristics except for the 2.2μF capacitor.
Test Differential Input Pin
VINM (Input)
This is a test pin. This signal functions as a differential input pin of VINP input at the test. Normally
connect it to AVSS.
