There are so many VRs and jumpers that if makes QC and re-calibration very difficult. Every
step must be handled manually, meaning that calibrating these D/A boards is not an
enjoyable task.
When we designed the PEX-DA and PISO/PIO-DAxU series, we tried to remove many/the
these majorities of VRs and jumpers, but still retain the same precision and performance. In
the long run, we selected a 14-bit D/A converter and adapted the software calibration to
provide at least the same performance and precision as the A-626/A-628:

All these VRs and jumpers have been removed.
All calibrations can be performed using software.
All channel configurations can be selected using software, meaning that there is no need
to change any hardware.
Precision is at least the same as the A-626/A628.
All 16 channels can be configured and used in different configurations at the same time.
(For example, channel_0=
10 V, channel_1=4~20 mA, channel_2=0~5 V, etc)
All these features can be implemented on a small, compact and reliable half-size PCB.
