NOTES: (1) If V
SS
= 0V, specification applies at code 00A
H
and above. (2) LSB means Least Significant Bit, with V
REFH
equal to +2.5V and V
REFL
equal to –2.5V,
one LSB is 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 step from code 000
H

or vice-versa. If V
SS
= 0V, full-scale positive step from code 000
