Hi.

I've connected the AD5761 as from attached file.
For the programming of the AD5761, I did the following steps:

- write to control register 0x04 00 03 //external reference voltage (2,5V), output range =10V

- sotware full reset 0x0f 00 00

I load the input dac register with 0xffff data to get 10V on Vout

- write to input register 0x01 ff ff

- write to update dac register 0x02 00 00

is it correct?

The Vout is always 0V, the signals seem to me correct.

I don't understand where is my error

 

best regards

Renato
