Outputs
The MAX5180 outputs are designed to supply full-scale
output currents of 1mA into 400
loads in parallel with
a capacitive load of 5pF. The MAX5183 features inte-
grated 400
resistors that restore the array currents to
proportional, differential voltages of 400mV. These dif-
ferential output voltages can then be used to drive a
balun transformer or a low-distortion, high-speed oper-
ational amplifier to convert the differential voltage into a
single-ended voltage.

Definitions
Integral Nonlinearity
Integral nonlinearity (INL) (Figure 5a) is the deviation of
the values on an actual transfer function from either a
best-straight-line fit (closest approximation to the actual
transfer curve) or a line drawn between the endpoints
of the transfer function once offset and gain errors have
been nullified. For a DAC, the deviations are measured
every single step.
Differential Nonlinearity
Differential nonlinearity (DNL) (Figure 5b) is the differ-
ence between an actual step height and the ideal value
of 1LSB. A DNL error specification of less than 1LSB
guarantees no missing codes and a monotonic transfer
function.
Offset Error
Offset error (Figure 5c) is the difference between the
ideal and the actual offset point. For a DAC, the offset
point is the step value when the digital input is zero.
This error affects all codes by the same amount and
can usually be compensated by trimming.
