Hi Masanori,
Please use DAC5672A datasheet which has the thermal information. http://www.ti.com/lit/ds/symlink/dac5672a.pdf page 6 and there is a foot note (1) with a link which will help you with the calculations.
DAC5672 and DAC5672A are basically the…
Hi Yang,
Yes for use case DAC5672A in single bus interleaved mode will be perfect. Please use DAC5672A instead of DAC5672. DAC5672 is not recommonded for new design.

Neeraj
Hi Toshiyuki,
The main difference between DAC5672A and DAC5672 voltage difference between AVDD and DVDD. DAC5672 allows max voltage difference between AVDD and DVDD to be -0.5V to +0.5V. Where as in case of DAC5672A max allowable voltage difference between…
Ok, Thanks
I checked the DAC5672A's datasheet and I found a schematic and the Layout as below:
(page 18 and 25)

actually I want to send digital data from a FPGA to the DAC. I see some termination resistors at the input…
Hi Patryk, Please take a look at DAC5652A. www.ti.com/.../dac5652a . The update rate is 275MSPS and it is parallel CMOS device. DAC5652A is 10 BIT device but the same family also has 12 BIT(DAC5662A) and 14 BIT (DAC5672A). Regards, Neeraj
Hi Pavanbabut,
Looking at the picture you sent me, the board is setup to output single ended output signal on J1 and J2. Can you please explain what you mean by pin 29 of J10 is connected to J3?
Also please make sure you are meeting setup and hold…
Part Number: DAC2904 Other Parts Discussed in Thread: DAC5672 , DAC5672A Hi, Team,
Is there the DAC2904 EVM? A customer would like to evaluate the DAC2904, but it seems that the DAC2904 does not exist now.
Best Regards,
Satoshi Yone
Hi Takumi,
Please recommend using the DAC5672A - it has same performance, but does not have as strict power sequence requirements. The AVDD and DVDD can come up independently.
The AVDD-DVDD maximum voltage difference requirement on DAC5672 is +/-0…
Hi,
I did a quick scan of the datasheets and it appears that this should work fine. In fact, figure 18 of the datasheet indicates that the mode pin has a 100 kOhm internal pullup resistor. So it looks like the part will work even if pin 48 is left floating…
Hi Mesh,
Yes there is no problem with the figure 22 in the datasheet.
Here is the link to the application note. Section 2.3 talks about how the compliance voltage for the DAC is calculated.
Regards,
Neeraj
