ADC Conversion Result
214
ATmega16(L)
After the conversion is complete (ADIF is high), the conversion result can be found in
the ADC Result Registers (ADCL, ADCH).
For single ended conversion, the result is
where V
ence (see Table 83 on page 215 and Table 84 on page 216). 0x000 represents ground,
and 0x3FF represents the selected reference voltage minus one LSB.
If differential channels are used, the result is
where V
input pin, GAIN the selected gain factor, and V
result is presented in two’s complement form, from 0x200 (-512d) through 0x1FF
(+511d). Note that if the user wants to perform a quick polarity check of the results, it is
sufficient to read the MSB of the result (ADC9 in ADCH). If this bit is one, the result is
negative, and if this bit is zero, the result is positive. Figure 111 shows the decoding of
the differential input range.
Table 82 shows the resulting output codes if the differential input channel pair (ADCn -
ADCm) is selected with a gain of GAIN and a reference voltage of V
