(1) 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 input up to the
maximum full scale range. The flag automatically resets when within the normal operating range unless configured to latch.
(2) 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.
(3) Includes offset, gain, drift, non-linearity and repeatability error terms.
(4) Output ripple is the amount a fixed output varies with time, assuming a constant load and temperature.
(5) Repeatability is the ability of the output module to reproduce output readings when the same controller value is applied to it consecutively, under the same conditions and
in the same direction.
