D/A CONVERTER CHARACTERISTICS
(See pg. 5 for standard conditions)
Notes: 1. LSB is defined as
divided by the resistance between R1 or R2 to Vss.
2. Offset
DAC
: The Offset of a DAC is defined as the deviation between the measured and ideal output, when the DAC input is 01h. It is
expressed in LSB.
FSError
DAC
: The Full Scale Error of a DAC is defined as the deviation between the measured and ideal output, when the input is FFh. It
is expressed in LSB. The Offset
DAC
is subtracted from the measured value before calculating FSError
DAC
.
DNL
DAC
: The Differential Non-Linearity of a DAC is defined as the deviation between the measured and ideal incremental change in
the output of the DAC, when the input changes by one code step. It is expressed in LSB. The measured values are adjusted for Offset
and Full Scale Error before calculating DNL
DAC
.
INL
DAC
: The Integral Non-Linearity of a DAC is defined as the deviation between the measured and ideal transfer curves, after adjust-
ing the measured transfer curve for Offset and Full Scale Error. It is expressed in LSB.

These parameters are periodically sampled and not 100% tested.
