  • ADS122C04: fail to read back configuration register

    TI Thinks Resolved
    Part Number: ADS122C04 Hi Sir, My customer would like to read back configuration register 00h to 03h. Customer fails to read back 00h and 01h but they can read back 02h and 03h data = 0x00. Is there anything wrong? Any difference we should do when reading…

  • ADS122C04: Idle Tones

    Part Number: ADS122C04 Other Parts Discussed in Thread: ADS1210 Hello, I have an application where I suspect I am running into Idle Tones. We do Gas Chromatography, where the front end is super quiet and we use all the bits. In the 26 years I have been…

  • ADS122C04: Issues reading Pyranometer output

    Resolved
    Part Number: ADS122C04 Hey guys, Recently we've been trying out the ADS122c04 in some applications, and recently we've been trying to make some Pyranometer readouts. Due to a request from the final client, there are no biasing resistors on the…

  • RE: ADS122C04: Current Consumption increases during conversion

    Hi Bob, Thank you for your reply and confirm the EVM. I understand no current increase was observed when ADS122C04 was turned on. I'll share this information with the customer and look into the influence from the other pins include input(analog) and output…

  • ADS122C04: Restarting conversions in continuous-conversion mode

    Resolved
    Part Number: ADS122C04 Hi, We would like to use the continuous conversion mode of the ADS122C04 to implement interleaved sampling of three channels. It seems that we can implement this by first configuring all the configuration registers and then only…

  • ADS122C04: ADS122C04 single ended mode

    TI Thinks Resolved
    Part Number: ADS122C04 The ADS122C04 data sheet says to bypass the PGA in single ended mode. In our single ended photodiode application, enabling the PGA seems to reduce noise (possibly due to the internal chopper amp?). What are the consequences of using…

  • ADS122C04: Timing information for turbo mode

    Resolved
    Part Number: ADS122C04 Hi Team, Good day. I have a question about the ADC ADS122c04. How long does it take in turbo mode at an output data rate of 1200 to measure all 4 inputs once? Or how long does it take to switch from one input to the other. So how…
