Electrical Characteristics for the A/D Converter
(1) 8/10-bit A/D Converter
(VCC
= 4.0 V to 5.5 V, AVRH2 = 4.0 V to 5.5 V, VSS = AVSS10 = 0 V, TA = 40 °C to + 85 °C)
*1 : When VCC
= AVCC10 = 5.0 V and peripheral clock = 33 MHz
*2 : The current when the CPU is in stop mode and the A/D converter is not operating (at VCC
= AVCC10 =
AVRH2
= 5.0 V) .
Notes :
The above figures do not guarantee the accuracy between each unit.
Output impedance of the external circuit ≤ 2 kΩ.
The result of 8/10 bit A/D conversion is not guaranteed at the voltage of VCC = 2.7 V to 4.0 V.
