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
Input (limited to +5V) See *Note.
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 the pins are limited to 35 Volt input/output!!! However, there are protections, please take
precautions in order to avoid damage of the main board.
* Note: Some pins are protected and limited to 5 Volt!!! However, there are Protections, please take
precautions in order to avoid damage of the main board.
2.4. Application Connector
There are two ways to connect the application to PTC04:
2.4.1. The DB15_Female connector (application connector)
