NOTES: (1) If VSS = 0V, specification applies at code 004H and above. (2) LSB means Least Significant Bit, when VREFH equals +10V and VREFL equals 0V, then
one LSB equals 2.44mV. (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) Full-scale positive 10V step and negative step from code FFFH to 004H.
