5. Electrical Characteristics
REJ03B0274-0110 Rev.1.10 Sep 28, 2009
Page 31 of 54
Under development Preliminary specification
Specifications in this manual are tentative and subject to change.
Notes:
1. VCC/AVCC = Vref = 2.7 to 5.5 V and Topr =
20 to 85°C (N version), unless otherwise specified.
2. This applies when one D/A converter is used and the value of the DAi register (i = 0 or 1) for the unused D/A converter is 00h.
The resistor ladder of the A/D converter is not included.
Notes:
1. VCC = 2.7 to 5.5 V and Topr =
20 to 85°C (N version), unless otherwise specified.
2. When the digital filter is disabled.
Notes:
1. VCC = 2.7 to 5.5 V and Topr =
20 to 85°C (N version), unless otherwise specified.
2. When the digital filter is disabled.
