Figure 21-17. Amplifier synchronization timing diagram
In order to have a better understanding of the functioning of the amplifier synchronization, a tim-
ing diagram example is shown
It is also possible to auto trigger conversion on the amplified channel. In this case, the conver-
sion is started at the next amplifier clock event following the last auto trigger event selected
thanks to the ADTS bits in the ADCSRB register. In auto trigger conversion, the free running
mode is not possible unless the ADSC bit in ADCSRA is set by soft after each conversion.
The block diagram of the two amplifiers is shown on
