DAC53701: DAC Update

Part Number: DAC53701

I am thinking of using it in such a way that the output changes frequently during operation.

To change the output of the DAC, the register “DAC_DATA ” must be rewritten.
This is non-volatile memory and is not guaranteed to be rewritten more than 20,000 times.
Is this understanding correct?

If I want to rewrite more than 20,000 times with this device, is there any way?

Thanks,

Please let me know if there is a way to write directly to DAC_BUFFER.

Hi,

DAC_DATA is written into register address space 0x21. A normal write will not have any effect on NVM.

NVM write will only happen if you write trigger register, after the DAC_DATA write.

Example code:

WRITE DAC_DATA(0x21), 0x05, 0x54  //  Write into DAC buffer

WRITE TRIGGER(0xD3), 0x04, 0x18  //   Write the above into NVM
