Re: [avr-gcc-list] AVR Voltage Reference

[Douglas Dotson]

That's pretty much the same graph that is in the
Tiny15 manual. It does'nt really relate the
accuracy to temperature.

&gt; &gt; In other words, can I calibrate out the
error,
&gt; &gt; or does it vary during operation?
&gt; 
&gt; Yes, it's stable over time, though not initially
&gt; accurate.
&gt; 
&gt; It has some sensitivity to Vcc and temperature;
I've
&gt; attached a graph I got
