Explanations to the Output range
Balancing the offset and the amplification is done for the PCD3.W6x5 digitally by the
µC. Because there is no potentiometer the output range has been slightly enlarged to
cover also maximum values in the worst case.
Typical output range (w/o tolerances of components):
W605:
-0.26 V...+10.36 V (instead of 0...+10 V)
W615:
0 mA...21.4 mA (instead of 0...20 mA)
W625:
-10.62 V...10.36 V (instead of -10 V...+10 V)
This range corresponds with 10 bit (1024 steps) as before. The result is the following
LSB resolution:
W605:
1 LSB = 10.38 µV
W615:
1 LSB = 21.7 µA
W625:
1 LSB = 20.75 µV
