Part Number: DDC118 We have a product with a DDC118. Some units shows a behavior where the zero offset level starts at a level and after a period of time start to jump up to a new level. During a transition time the level makes jumps up and down between…
Part Number: DDC118 Hi Team,
My customer is using DDC118 for light analysis and would like to seek for some advise on the following:
Should we choose continuous mode or non-continuous mode ? Our test will collect data only when user press start…
Hi Edu,
We only log the data in what I circled. As for previous two cycles including the short pulse, we got DVALID and s/w clock out two bits but does not record it. We tried not clocking the data and found it does not impact what are read out in…
Hey Edu. Here's a photo of our DDC118 PCB with the Triax attached. Closest to camera is a bare wire connecting inner shield to the board's coax returns. Below that is an orange wire used to extend the center conductor & tie the two channels. I mis-spoke…
Hi Sunny,
Welcome to TI E2E forum!
DDC118 supports serial interface and not SPI protocol. Thanks for pointing it out and we are working on fixing it.
Please refer to the DDC118 datasheet for the serial timing specifications.

Hi Don,
How are you?
Thank you for helping the customer using DDC118 device.
We will look into the customer's question and
will reply to you very soon.
Thank you very much!
Have a very nice day!
Best regards,
Chen
Part Number: DDC118 I'd like to cascade two DDC118 chips but Figure 21 "Daisy-Chained DDC118s" in the datasheet only shows the serial data line connections. What does one do with the DValid and Conv signals (or any others that may be affected by daisy…
Part Number: DDC118 I need help with interpreting the typical characteristics performance curves in page 6 and 7 of the datasheet. I know what the underlying terms and definitions are, but I need to understand why the curve is in that particular way.
Part Number: DDC118 Hi,
In DDC118 datasheet, parametric table, it mentioned that the DC Bias Voltage is +/-0.05mV typical.
The definition of the DC Bias voltage is "voltage produced by the DDC118 at its input which is applied to the sensor", which…
