MB90340E Series

11.5 A/D Converter

(TA

 40°C to 105°C, 3.0 V AVRH  AVRL, V

CC  AVCC  5.0 V  10, fCP 24 MHz, VSS  AVSS  0 V)

*: If the A/D convertor is not operating, a current when CPU is stopped is applicable (VCC  AVCC  AVRH  5.0 V) .

Note:

: The accuracy gets worse as |AVRH

 AVRL| becomes smaller.
