AD5429/AD5439/AD5449 POR Voltage

Hi HM72 ,

The POR threshold voltage for the device is not explicitly listed inthe datasheet. It only mentions that the devices operate over a supply range of 2.5 V to 5.5 V, and the POR feature ensures that the DAC outputs are initialized to zero scale on power-up.

Let me check further if we have design documentations that might be able to help. I will get back to you soon.

Hi HM72 ,

I couldn’t find exact documentation on the Power-on Reset (POR) threshold for this device. However, it is typically triggered near the minimum VDD (around 2.5V). Typically, the POR initializes the outputs to zero scale when the supply crosses this threshold.

Hi, Den,

Thank you for your information.

I understand that POR is triggered below the minimum voltage of VDD.
