D/A CONVERTER CHARACTERISTICS (See pg. 4 for Standard Conditions)
Notes: 1.
DAC input Byte = FFh, Source or sink mode.
2.
LSB is defined as
divided by the resistance between R1 or R2 to Vss.
3.
OffsetDAC: 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.
FSErrorDAC: 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 OffsetDAC is subtracted from the measured value before calculating FSErrorDAC.
DNLDAC: 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 DNLDAC.
INLDAC: 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.
4.
These parameters are periodically sampled and not 100% tested.
5.
V(I1) and V(I2) are VCC - 1.2V in source mode and 1.2V in sink mode. In this range the current at I1 or I2 varies <1%.
6.
The maximum current, sink or source, can be set with an external resistor to 3.2 mA with a minimum VCC = 4.5V. The compliance volt-
age changes to 2.5V from the sourcing rail, and the current variation is <1%.
