Description
Output of the high current Programmable Supplies
Output of the Fast DAC Programmable Power Supply
Outputs (Driver outputs before Rsens) for current evaluations.
These outputs could be used to connect to the analog comparators in order to
create fast digital signals based on current.
There are 4 differential inputs for making measurements, these are the positive
inputs.
The negative inputs of ExtMeas1- 4Pos
See *Note.
Input (limited to +5V)
Fast Level comparators in order to remove time consuming measurement
Supply to extend the daughter board with some extra drivers
Output of internal reference
Analogue Ground
Note: All pins are limited to 35V. Despite of these protections, please take precautions in order to
avoid damage of the main board.
Note: Some pins are protected and limited to 5 Volt! Despite of these protections, please take
precautions in order to avoid damage of the main board.
