Specification Definitions

DIFFERENTIAL NON-LINEARITY (DNL) is the measure of the maximum deviation from the ideal step size of 1

DAC-to-DAC CROSSTALK is the glitch impulse transferred to a DAC output in response to a full-scale change

in the output of another DAC.

DIGITAL CROSSTALK is the glitch impulse transferred to a DAC output at mid-scale in response to a full-scale

change in the input register of another DAC.

DIGITAL FEEDTHROUGH is a measure of the energy injected 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 (FFh) loaded

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 output 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 deviation 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 Electrical Characteristics.

LEAST SIGNIFICANT BIT (LSB) is the bit that has the smallest value or weight of all bits in a word. This value is

n

(1)

DAC088S085.

MAXIMUM LOAD CAPACITANCE is the maximum capacitance 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
