DAC8571: The output is fixed at 0V.

HIROYUKI UMINO

Part Number: DAC8571

Tool/software:

Hi Katlynne Jones san,

Thank you or your reply.
I don't have a load on the output.
I have not set a power down command to the device.
Can I just set EXAMPLE 4(Power-down DAC8571 with Hi-Z output) once at startup?
I will try an I2C read command to check.

Best,
Umino

HI Umino-san,

You want to make sure the DAC is powered on. If you aren't sending a power down command, then the default state is powered on. You can try example 4 to power down the DAC, and then either example 2 or 3 to set the DAC back to powered on in fast settling or low power mode.

Best,

Hi Katlynne san,

Thank you for your reply.

I tried example 4 and example 2.
The DAC8571 correctly outputs the set value.

Best,
