Converting Voltage to Raw Counts
To convert a voltage output value to a raw count, use one of the following
equations:
Bipolar:
Count = [(V
out
×
4096) / span] + 2048
Unipolar:
Count = (V
out
×
4096) / span
where V
out
is the output voltage and span is the span of the output
range.
For example,
assume that you want to specify an output voltage of 3V
for a DDA-16 that is set up for a ±5V bipolar output (10V span). The raw
count is determined as:
[(3
×
4096) / 10] + 2048 = 3277
Converting Current to Raw Counts
To convert a current output value to a raw count, use the following
equation:
Count = [(I
out
×
4096) / 16] - 1024
where I
out
is the desired current (in milliamperes).
For example,
assume that you want to specify an output current of 14mA
for a DDA-16. The raw count is determined as:
[(14
×
4096) / 16] - 1024 = 2560
