I use the LTC1592 converter according to this diagram.

The voltage Vref =OUT_STDINP=-10V

When I program this DAC in spi in range +5V with a data =FFFE the output voltage is -10V.

Why do I have -10V at the output?

What does the programming of the range correspond to Table 1 of the datasheet ?

Voir data SPI ci-dessous en fonctionnement 32 bits

What is the relationship between Vout and Vref and the programming of the DAC data?

Thanks for your help
