Part Number: DAC81416

Hi team,

We have following tdacwait spec listed as below and the value is 2.4us.

How to understand this sequential DAC update and the following sychronous update delay.

Seems it's different results: 2.4us vs 1us.

Could you pls help to share some comments for better undestanding？

Thanks

Best regards

Mia

Hi Mia,

There is a mistake in the data sheet. Please check the clarification below -

- Asynchronous mode - minimum wait time is 2.4us for sequential update, between the SYNC rise edge and next DAC code update

- Synchronous mode - minimum wait time is 2.4us for sequential update, between the LDAC fall edge and next DAC code update

Thanks,

Sanjay
