17. Recommended External Application Circuits
1) Power supply stabilizing capacitors
Connect capacitors between 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 capacitors
It is recommended that capacitors with 1μF or lager be connected between VSS and the AGND
and AGNDIN pins to stabilize the AGND signal. The capacitors must be placed as close to the
pins as possible.
