T Specification same as grade to the left.

NOTES: (1) If VSS = 0V, specification applies at code 00AH and above. (2) LSB means Least Significant Bit, with VREFH equal to +2.5V and VREFL 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 VSS = –5V, full-scale step from code 000H to FFFH or vice-versa. If VSS = 0V, full-scale positive step from code 000H to FFFH and negative step from code

FFFH to 00AH.
