7.14.1 Features
7.15 Internal voltage reference
The internal voltage reference is an accurate 0.9 V and is the output of a low voltage band
gap circuit. A typical value at T
the 0 C to 85 C temperature range (see
reference can be used in the following applications:

10-bit successive approximation ADC.
Input multiplexing among 8 pins.
Power-down mode.
Measurement range 0 V to V
10-bit conversion time  2.44 s (up to 400 kSamples/s).
Burst conversion mode for single or multiple inputs.
Optional conversion on transition of input pins ATRG0 or ATRG1, timer match signal,
or comparator output. (Input signals must be held for a minimum of three system clock
periods). Also see
Individual result registers for each ADC channel to reduce interrupt overhead.
