# Accuracy of a dac - INL rating how that relates to deviation in mV's

In the datasheets of a dac they talk about the INL error. As I understand this is to do with how much the output of the dac deviates from the output of an ideal DAC. So I was wondering how does that translate to how much the voltage will deviate in mV's? I'm using a MCP4922. The datasheet say it can be as high as +/- 12LSB.

$V_{INL}=\frac{INL}{2^n}*V_{fullscale}$ will get you what you want. Where N = number of bits.
