Part Number: DAC63204

Hi Team,

This post is related to our customer's application of DAC63204 with TLC59401RHBR which I post in the link below.

Here is his concern about DAC63204,

I am also looking at the DAC63204. I could have an external circuit to pull the feedback pin high to turn off the current output. How fast is the feedback on the DAC63204? 

Regards,

Danilo

    Hi Danilo,

    You can use the GPIO pin, not the FB pin, to turn the current output on/off. 

    There is a 2us delay for the change on the GPIO pin to the command being executed. 

    Here are the list of commands that the GPIO pin can be configured for: 

    Best,
