The Atmel
verter (ADC). The ADC is connected to 8-pin port A for external sources. In addition to
external sources, the internal temperature sensor can be measured by the ADC. The analog
multiplexer allows 8 single-ended channels or 12 differential channels from port A. The pro-
grammable gain stage provides amplification steps 0dB (1x) and 26dB (20x) for 12 differential
ADC channels.
The ADC contains a sample-and-hold circuit which ensures that the input voltage to the ADC
is held at a constant level during conversion. A block diagram of the ADC is shown in
18-1 on page
And internal reference voltage of nominally 1.1V is provided on chip. Alternatively, VCC can
be used as reference voltage for single-ended channels. There is also an option to use an
external voltage reference and turn off the internal voltage reference.
