ATtiny88 features a 10-bit, successive approximation Analog-to-Digital Converter (ADC). The
ADC is wired to a nine-channel analog multiplexer, which allows the ADC to measure the volt-
age at six (or eight, in 32-lead packages) single-ended input pins and from one internal,
single-ended voltage channel coming from the internal temperature sensor. Single-ended volt-
age inputs are referred to 0V (GND).
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
There is a separate analog supply voltage pin for the ADC, AV
nected to the ADC via a passive switch. The voltage difference between supply voltage pins V
and AV
the analog suplly voltage pin.
Internal reference voltage of nominally 1.1V is provided on-chip. Alternatively, V
as reference voltage.
