Overall Accuracy

(4)

±0.5% full scale at 25°C

(1)

Conducted Immunity frequency range may be 150 kHz to 30 MHz if the Radiated Immunity frequency
range is 30 MHz to 1000 MHz.

(2)

The over- or under-range flag will come on when the normal operating range (over/under) is
exceeded. The module will continue to convert the analog output up to the maximum full scale range.
The flag automatically resets when within the normal operating range unless configured to latch.

(3)

Step response is the period of time between when the D/A converter was instructed to go from
minimum to full range until the device is at 63% of full range.

(4)

Includes offset, gain, drift, non-linearity and repeatability error terms.
