Part Number: DAC61404 Other Parts Discussed in Thread: DAC81404 , DAC81402 , DAC61402 Hi Experts,
Seeking your assistance on this query from Cx about DAC61404 device ID.
I'm currently working with the DAC61404 to create a threshold voltage for a comparator…
Part Number: DAC61404 I asked the question earlier if unequal voltages could be utilized when using the sense lines and was told it would be fine. We are seeing the devices latch up. When there is an offset on the sense lines I am seeing the device latch…
Part Number: DAC61404 I can read/write the SPICONFIG register (and read-back to confirm), but whenever I write to the DACPWDWN register it only ever reads back as 0xFFFF. According to the datasheet the lower 4 bits are R/W. Specifically, I am trying to…
Part Number: DAC61404 I would like to run the DAC in the 0-40V mode using up to 30V output. I also need to support compensation for the negative sense line to -2V with respect to the GNDs. Since the bipolar setup is only to +20Vout, I would like to run…
Hi Archie,
Yes this is a known issue and we have it on our list to update.
The correct device ID for the DAC81404 is 0x29C (or 0xA70 if you left shift by 2). Correct device ID is 0x24C for the DAC61404.
Best,
