Part Number: DAC7731 Tool/software: Hi All,
Good day.
MAy I know what is the correct marking for this PN# DAC7731EC?
I got the parts with top marking "DAC7731E" instead of "DAC7731EC". See attachment.
However, I think the correct one should…
Part Number: DAC7731 Hi, I'm having this part : DAC7731EC/1K (Date Code: 2325)
Datasheet: Marking :

1) However my physical part marking does not have the "C". Was this remove as per the PCN.
What is the C stand for and if my part…
Part Number: DAC7731 Dear Expert
This is the schematic diagram before the change. We tested that applying surge interference would cause abnormal output of pin 11 .
The customer changed RSTSEL to add a pull-down 10K resistor, and RST to add a power…

Part Number: DAC7731 Hi team,
One of our customers has the following questions:
When the output of dac7731 is designed to be 0-10V and the internal reference is used, the REFEN pin is suspended and not connected to GND.
Previously, more than 100…
Part Number: DAC7731 Other Parts Discussed in Thread: TPS7A39 Hi,
I understand that the recommended supply sequence is VSS -> VCC -> VDD as comment below from DS.
The following supply sequence must be followed: VSS (device substrate) first, then…
Part Number: DAC7731 Hi,
we are using DAC7731EC (3Nos) in our application. Datasheets suggests to follow powers up sequence as VSS followed by VDD and then VCC. Please let us know what would be the consequences if power up sequence is missed.
Thanks…
Hi Neel,
Thank you for your query. The DAC7731 supports SPI. SDI corresponds to MOSI and SDO corresponds to MISO in standard SPI terminology.
Hope that answers.
