(Note)
The capacitance of the AVREF capacitor (C5) affects the AVREF rise time and analog characteristics. If
weight is given to the analog characteristics, specify 4.7
μ
F, and if it is given to the AVREF rise time, specify
2.2
μ
F. The electrical characteristics for the analog characteristics that are described above are guaranteed in
both capacitances.
