14.5 Interrupts
The A/D converter generates an interrupt (ADI) at the end of A/D conversion. The ADI interrupt
request can be enabled or disabled by the ADIE bit in ADCSR.
14.6 Usage Notes
When using the A/D converter, note the following points:
1.
2. Relationships of AV

Analog Input Voltage Range: During A/D conversion, the voltages input to the analog input
pins should be in the range AV
related as follows: AV

Failure to observe points 1, 2, and 3 above may degrade chip reliability.
Note on Board Design: In board layout, separate the digital circuits from the analog circuits
as much as possible. Particularly avoid layouts in which the signal lines of digital circuits
cross or closely approach the signal lines of analog circuits. Induction and other effects may
cause the analog circuits to operate incorrectly, or may adversely affect the accuracy of A/D
conversion.

Note on Noise: To prevent damage from surges and other abnormal voltages at the analog
input pins (AN
like the one in figure 14-7 between AV

AV
to the analog input pins (AN
can also occur if A/D conversion is frequently performed in scan mode so that the current that
charges and discharges the capacitor in the sample-and-hold circuit of the A/D converter
becomes greater than that input to the analog input pins via input impedance Rin. The circuit
constants should therefore be selected carefully.
