The ATtiny24/44/84 features a 10-bit successive approximation ADC. The ADC is connected to
8-pin port A for external sources. In addition to external sources internal temperature sensor can
be measured by ADC. Analog Multiplexer allows eight single-ended channels or 12 differential
channels from Port A. The programmable gain stage provides ampification steps 0 dB (1x) and
26 dB (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
on page
Internal reference voltage of nominally 1.1V is provided On-chip. Alternatively, V
as reference voltage for single ended channels. There is also an option to use an external volt-
age reference and turn-off the internal voltage reference.
