MB90620A Series
5. A/D Converter Electrical Characteristics
(AVCC = VCC = +2.7 V to 5.5 V, AVSS = VSS = 0.0 V, +2.7 V
≤ AVRH – AVRL, TA = –40°C to +85°C)
* : Current when the A/D converter is not operating and the CPU is stopped (when VCC = AVCC = AVRH = +5.5 V)
Notes:
The smaller | AVRH – AVRL |, the greater the error would become relatively.
The output impedance of the external circuit for the analog input must satisfy the following conditions:
The output impedance of the external circuit should be less than approximately 7 k
.
If the output impedance of the external circuit is too high, an analog voltage sampling time might be
insufcient (sampling time = 5
s @ at a machine clock of 12 MHz).
