Recommended External Application Circuits
1) Power supply stabilizing capacitance
Connect capacitors between the VDD and VSS pins to eliminate ripple and noise included in power supply.
For maximum effect, the capacitors should be placed at a shortest distance between the pins.

2) AGND stabilizing capacitance
It is recommended that a capacitor with 1.0μF or larger be connected between the AGND pin and VSS to
stabilize the AGND signal. The capacitor should be placed as close to the AGND pin as possible.
