8.2 Analog outputs
There are 4 analog output channels with 12-bit resolution on the board.
The analog outputs are updated through 32-bit write operations on I/O
addresses. A stauts bit (DAC ready) indicates if the analog output channels
are ready to be updated.
The time ("Time to ready"; see figure below) between the write operations
on I/O addresses (DAC registers) and the update of the analog outputs
amounts typically 4.5 µs. Further accesses on the DAC registers are not
handled within this interval.
The time between the writing of a software command and the reaching of
the setpoint value by the analog outputs is typically 15 µs (settling time).
