VDD1, VSS1 Terminal condition
It is necessary to place capacitors between VDD1 and VSS1 as describe below.
• Place capacitors as close to VDD1 and VSS1 as possible.
• Place capacitors so that the length of each terminal to the each leg of the capacitor be equal (L1 = L1’, L2 = L2’).
• Place high capacitance capacitor C1 and low capacitance capacitor C2 in parallel.
• Capacitance of C2 must be more than 0.1μF.
• Please mount a suitable capacitor about C1.
• Use thicker pattern for VDD1 and VSS1.

AVDD, AVSS Terminal condition
It is necessary to place capacitors between AVDD and AVSS as describe below.
• Place capacitors as close to AVDD and AVSS as possible.
• Place capacitors so that the length of each terminal to the each leg of the capacitor be equal (L3 = L3’).
• Capacitance of C3 must be more than 1μF.
• Use thicker pattern for AVDD and AVSS.
