How many is LTC2000 dac output COMMON MODE VOLTAGE？

Hi applo168 ,

Thank you for your patience.

The output common-mode voltage of the LTC2000 can be estimated by taking half of I_OUTFS [i.e., I_CM = (I_OUTFS/2) + I_OUTCM] and multiplying the resulting value with R_LOAD. Kindly refer to p. 25 of the datasheet for the related formulas. Note that I_OUTCM is a small value (0.2% of full-scale) added on top of both I_OUTP and I_OUTN and is different from I_CM. Moreover, the output compliance range of the LTC2000 is -1 V to +1 V, which means the common-mode voltage plus/minus the peak signal swing should be within this range.
