ATMega8 ADC resolution increase by oversampling
For applications requiring lower sampling rates but higher resolution, Atmel note AVR121 describes methods for oversampling and decimation. The sample application uses a ATMega16, but the code is easily adapted to an ATMega8.
The resolution can be increased as high as 16 bit, but with a considerably reduced sampling rate. This could be useful in small scientific instruments where the higher accuracy is required, but only a few samples per second is sufficient. (Device ATmega8)
