Question

What is the output value for an Input of 10000010 if an 8-bit DAC has a full-scale output of 10mA?

Answer 1

I don't do homework, but a few hints are: do your math in decimal, and 10ma is 2 to the power 8 minus 1.  eeew fractions.

Answer 2

Without the datasheet for the specific DAC, its impossible to answer accurately! Also, the full-scale output current of 10mA doesn't really have any bearing on the output value.

However, assuming it is a "Reset to Zero" type DAC that operates on a 2.5V ~ 5.5V Vcc and has a full-scale Vout of 2.5V, then an input of 10000010 would give an output of 1.3V.
