The Atmel
nected to a 11-channel Analog Multiplexer which allows 16 differential voltage input
combinations and 11 single-ended voltage inputs constructed from the pins PA7..PA0 or
PB7..PB4. The differential input is equipped with a programmable gain stage, providing ampli-
fication steps of 8x or 20x on the differential input voltage before the A/D conversion. The
single-ended voltage inputs refer to 0V (AGND).
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
4-82.
Internal reference voltages of nominally 1.1V or 2.56V are provided On-chip. Alternatively,
AVcc can be used as reference voltage for single ended channels. There are also options to
output the internal 1.1V or 2.56V reference voltages or to input an external voltage reference
and turn-off the internal voltage reference. These options are selected using the REFS[1:0]
bits of the ADMUX control register and using AREFEN and XREFEN bits of the AMISCR con-
trol register.
