INL, DNL, and total unadjusted error (TUE) are the most important specifications for PLC and other
process control systems. The MAX15500 is highly flexible and configurable to meet the needs of various
applications. Measurements of DNL, INL, and output error for the reference design are shown in Figure
3, Figure 4, and Figure 5, respectively. The data was taken at +25°C in the -10V to +10V voltage
output mode, with 5% overrange.
