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.
