Electrical Characteristics for the A/D Converter
(MB90567/568/F568 : TA
= 40 °C to +85 °C, 2.7 V ≤ AVR, VCC = AVCC = 2.7 V to 3.6 V, VSS = AVSS = 0.0 V)
(MB90V560 : TA
= +25 °C, 3.0 V ≤ AVR, VCC = AVCC = 3.0 V to 3.6 V, VSS = AVSS = 0.0 V)
* : Current when A/D converter is not used and CPU is in stop mode (VCC
= AVCC = AVR = 3.3 V)
Notes :
The L reference voltage is fixed to AVSS. The relative error increases as AVR becomes smaller.
Ensure that the output impedance of the external circuit connected to the analog input meets the following
condition :
Output impedance of MB90F568 external circuit
≤ 14 k (Sampling Time = 4 s)
Output impedance of MB90567/568 external circuit
≤ 7 k (Sampling Time = 4 s)
If the output impedance of the external circuit is too high, the analog voltage sampling time may be too short.
