Relative Accuracy or Integral Nonlinearity (INL)
For the DAC, relative accuracy or INL is a measure of the
maximum deviation, in LSBs, from a straight line passing
through the actual endpoints of the DAC transfer function.
Typical INL vs. code plots can be seen in Figure 14, Figure 15,
and Figure 16.
Differential Nonlinearity (DNL)
DNL 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 mono-
tonicity. This DAC is guaranteed monotonic by design. Typical
DNL vs. code plots can be seen in Figure 17, Figure 18, and
Gain Error
This is a measure of the span error of the DAC (including any
error in the gain of the buffer amplifier). It is the deviation in
slope of the actual DAC transfer characteristic from the ideal,
expressed as a percentage of the full-scale range. This is
illustrated in Figure 11.

Offset Error
This is a measure of the offset error of the DAC and the output
amplifier. It is expressed as a percentage of the full-scale range.
If the offset voltage is positive, the output voltage is still positive
at zero input code. This is shown in Figure 12. Because the
DACs operate from a single supply, a negative offset cannot
appear at the output of the buffer amplifier. Instead, there is
a code close to zero at which the amplifier output saturates
(amplifier footroom). Below this code, there is a deadband over
which the output voltage does not change. This is illustrated in
