Specification Definitions
DIFFERENTIAL NON-LINEARITY (DNL)
is the measure of
the maximum deviation from the ideal step size of 1 LSB,
which is V
REF / 4096 = VA / 4096.
DIGITAL FEEDTHROUGH
is a measure of the energy inject-
ed into the analog output of the DAC from the digital inputs
when the DAC outputs are not updated. It is measured with a
full-scale code change on the data bus.
FULL-SCALE ERROR
is the difference between the actual
output voltage with a full scale code (FFFh) loaded into the
DAC and the value of V
A x 4095 / 4096.
GAIN ERROR
is the deviation from the ideal slope of the
transfer function. It can be calculated from Zero and Full-
Scale Errors as GE = FSE - ZE, where GE is Gain error, FSE
is Full-Scale Error and ZE is Zero Error.
GLITCH IMPULSE
is the energy injected into the analog out-
put when the input code to the DAC register changes. It is
specified as the area of the glitch in nanovolt-seconds.
INTEGRAL NON-LINEARITY (INL)
is a measure of the de-
viation of each individual code from a straight line through the
input to output transfer function. The deviation of any given
code from this straight line is measured from the center of that
code value. The end point method is used. INL for this product
is specified over a limited range, per the Electrical Tables.
LEAST SIGNIFICANT BIT (LSB)
is the bit that has the small-
est value or weight of all bits in a word. This value is
LSB = V
REF / 2
n
where V
REF is the supply voltage for this product, and "n" is
the DAC resolution in bits, which is 12 for the DAC121S101.
MAXIMUM LOAD CAPACITANCE
is the maximum capaci-
tance that can be driven by the DAC with output stability
maintained.
MONOTONICITY
is the condition of being monotonic, where
the DAC has an output that never decreases when the input
code increases.
MOST SIGNIFICANT BIT (MSB)
is the bit that has the largest
value or weight of all bits in a word. Its value is 1/2 of V
A.
POWER EFFICIENCY
is the ratio of the output current to the
total supply current. The output current comes from the power
supply. The difference between the supply and output cur-
rents is the power consumed by the device without a load.
SETTLING TIME
is the time for the output to settle to within
1/2 LSB of the final value after the input code is updated.
WAKE-UP TIME
is the time for the output to exit power-down
mode. This is the time measured from the falling edge of 16th
SCLK pulse to when the output voltage deviates from the
power-down voltage of 0 V.
ZERO CODE ERROR
is the output error, or voltage, present
at the DAC output after a code of 000h has been entered.
