Electrical Characteristics for the D/A Converter
(VCC3
= DAVC = 3.0 V to 3.6 V , VCC2 = 2.3 V to 2.7 V , VSS = DAVS = AVSS = 0 V,
AVRH
= 3.0 V to 3.6 V , Ta = 10 °C to +70 °C)
*1 : No output occurs in the range DAVS to DAVS + 100 mV and DAVC to DAVC - 100 mV.
*2 : Current when D/A converter not operating and CPU in stop mode (VCC3
= DAVC = 3.6 V) .
