*1 : Supply current at AVCC5, if A/D converter and ALARM comparator are not operating,
(VDD5 = AVCC5 = AVRH = 5.0 V)
*2 : Input current at AVRH5, if A/D converter is not operating, (VDD5 = AVCC5 = AVRH = 5.0 V)
*3 : The current consumption per ADC macro is given here. On devices having more then one A/D converter, the
current values have to be multiplied by the number of macros.
Sampling Time Calculation
Tsamp = ( 2.6 kOhm + REXT)
× 11pF × 7; for 4.5V ≤ AVCC5 ≤ 5.5V
Tsamp = (12.1 kOhm + REXT)
× 11pF × 7; for 3.0V ≤ AVCC5 ≤ 4.5V
Conversion Time Calculation
Tconv = Tsamp + Tcomp
Definition of A/D converter terms
Resolution
Analog variation that is recognizable by the A/D converter.
Nonlinearity error
Deviation between actual conversion characteristics and a straight line connecting the zero transition point
(00 0000 0000B
00 0000 0001B) and the full scale transition point (11 1111 1110B 11 1111 1111B).
Differential nonlinearity error
Deviation of the input voltage from the ideal value that is required to change the output code by 1 LSB.
Total error
This error indicates the difference between actual and theoretical values, including the zero transition error,
full scale transition error, and nonlinearity error.
