Hello All,
I am currently playing with an Atmel Attiny84 uC. I am reading the ADC and using the internal 1.1V reference. I have a few questions regarding the 1.1V reference.
1) Does 1.1 ref depend on the operating voltage? The uC can run from 1.8-5.5V. Is it typically a constant 1.1V reference across the entire operating voltage range or does it change slightly with the operating voltage?
2)What circuitry is used to generate that 1.1V reference internally? I did not see this in the manual .
I have attached the manual in case it helps.
