  • DDC118: Saturation of one channel affects signal on other channel. But not all equally, and it seems, that some are not affected at all.

    Part Number: DDC118 Hi There, we just found out that saturating / FullScale Signals on one channel will affect the other input channels. Some show a slight increase of signal values, others even a drop. And, using a symmetrical CONV signal, it seems that…

  • DDC118: DDC A-B offset calibration using Testmode

    Part Number: DDC118 Hello, I have a question regarding the Cor rection of DDC A/B Mismatch and Noise Optimization / [FAQ] How to calibrate offset and gain in the DDC devices? Can we use the "testmode"-signal for calibration and offset-correction between…

  • DDC118: Only 4 channels visible

    TI Thinks Resolved
    Part Number: DDC118 Other Parts Discussed in Thread: DDC114 Hello, I've prepared a prototype with a DDC118 and I am able to read it out correctly. I'm using CLK = 4 MHz, DCLK = 4 MHz. When I'm reading the data on DOUT, it makes sense, but it corresponds…

  • DDC118: DDC118 / DDC112 Range change or setup timing

    Resolved
    Part Number: DDC118 Other Parts Discussed in Thread: DDC112 Hello, we are working on a design concept that probably includes either a ddc118 or ddc112. As we are coping with a high dynamic range of input current signals we want to know if it is possible…

    TI Thinks Resolved
    Part Number: DDC118 Other Parts Discussed in Thread: TMUX6136 We are considering the TMUX6136 in front of the DDC118 and willing to accept some degraded specs. The system is almost a DC response system so no high frequencies. We've looked at reed relays…

  • DDC118: Zero offset leve jumps

    TI Thinks Resolved
    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…

  • DDC118: Gang 2 channels to share current? We got noise.

    Part Number: DDC118 Other Parts Discussed in Thread: DDC232 , DDC264 Hey! We tied a current source to two channels in order to extend the input current range. It may not be much, but I could double the range if the channels shared the input current well…
