Notes on the output range
Balancingtheo󰀨setandtheamplicationisdoneforthePCD3.W6x5digitallyby
the µC. As there is no potentiometer, the output range has been slightly enlarged
to cover maximum values even in the worst case.
Typical output range (without component tolerances):
PCD3.W605: – 0.26 V…+ 10.36 V (instead of 0…+ 10 V)
PCD3.W615: 0 mA …21.4 mA (instead of 0…20 mA)
PCD3.W625: – 10.62 V … 10.36 V (instead of – 10…+10 V)
This range is broken down on a 10 bit scale (1024 steps), as before. The result is
the following LSB resolution:
PCD3.W605: 1 LSB = 10.38 µV
PCD3.W615: 1 LSB = 21.7 µA
PCD3.W625: 1 LSB = 20.75 µV
