TERMINOLOGY
Relative Accuracy
For the DAC, relative accuracy or integral nonlinearity is a
measurement of the maximum deviation, in LSB, from a
straight line passing through the endpoints of the DAC transfer
function. A typical INL vs. code plot is shown in Figure 5.
Differential Nonlinearity (DNL)
Differential nonlinearity is the difference between the measured
change and the ideal 1 LSB change between any two adjacent
codes. A specified differential nonlinearity of ±1 LSB maximum
ensures monotonicity. This DAC is guaranteed monotonic by
design. A typical DNL vs. code plot is shown in Figure 6.
Zero-Code Error
Zero-code error is a measurement of the output error when zero
code (0x0000) is loaded to the DAC register. Ideally, the output
is 0 mA. The zero-code error is always positive in the AD5821
because the output of the DAC cannot go below 0 mA. This is
due to a combination of the offset errors in the DAC and output
amplifier. Zero-code error is expressed in milliamperes (mA).
Gain Error
Gain error is a measurement of the span error of the DAC. It is
the deviation in slope of the DAC transfer characteristic from
the ideal, expressed as a percent of the full-scale range.
Gain Error Drift
Gain error drift is a measurement of the change in gain error
with changes in temperature. It is expressed in LSB/°C.
Digital-to-Analog Glitch Impulse
This is the impulse injected into the analog output when the
input code in the DAC register changes state. It is normally
specified as the area of the glitch in nanoamperes per second
(nA-s) and is measured when the digital input code is changed
by 1 LSB at the major carry transition.
Digital Feedthrough
Digital feedthrough is a measurement of the impulse injected
into the analog output of the DAC from the digital inputs of the
DAC, but it is measured when the DAC output is not updated.
It is specified in nanoamperes per second (nA-s) and measured
with a full-scale code change on the data bus, that is, from all 0s
to all 1s and vice versa.
Offset Error
Offset error is a measurement of the difference between ISINK
(actual) and IOUT (ideal) in the linear region of the transfer
function, expressed in milliamperes (mA). Offset error is
measured on the AD5821 with Code 16 loaded into the DAC
register.
Offset Error Drift
Offset error drift is a measurement of the change in offset error
with a change in temperature. It is expressed in microvolts per
degree Celsius (μV/°C).
