MAX5130/MAX5131
+3V/+5V, 13-Bit, Serial Voltage-Output DACs
with Internal Reference
_______________________________________________________________________________________ 5
Note 1: Accuracy is guaranteed as shown in the following table:
Note 2: Offset is measured at the code closest to 10mV.
Note 3: The temperature coefficient is determined by the “box” method in which the maximum
∆
V OUT over the temperature range is
divided by
∆
T.
Note 4: Accuracy is better than 1.0LSB for V OUT = 10mV to (V DD - 180mV). Guaranteed by PSR test on end points.
Note 5: R LOAD =
∞
and digital inputs are at either V DD or DGND.
