■ NOTES ON USAGE
• Countermeasures for switching noise
To prevent the switching noise riding on the analog output signal to the maximum possible extent, insert the
noise limiting capacitor between VCCA-A.GND pins, and between VCCD-D.GND pins closest as possible to the
IC pins.
• Power supply patterns
To reduce parasitic impedance, use the patterns as wide as possible to be connected to the VCCA, VCCD, A.GND
and D.GND pins.
