NOTES: (1) If V
= 0V, specification applies at code 00A
and above. (2) LSB means Least Significant Bit, when V
equals +2.5V and V
equals –2.5V,
then one LSB equals 1.22mV. (3) All DAC outputs will match within the specified error band. (4) Ideal output voltage, does not take into account zero or full-scale
error. (5) If V
SS
= –5V, full-scale 5V step. If V
SS
= 0V, full-scale positive 2.5V step and negative step from code FFF
