  • RE: ADS7253: Can ADS7253 and F28M35H52C communicate through SSI?

    Resolved
    Hello, I don't see a way to disable the interface in the BiSS C protocol (i.e. no /CS). Without that, I don't see a way to share the communication bus with the ADS7253. Regards,

  • CCS/ADS7253: Could we decrease the ADS7253 communication time?

    Part Number: ADS7253 Tool/software: Code Composer Studio The SPI clock we uses is 15Mhz. Now we send 3*16 bits(=48 bits, = 48 * 1/15 us = 3.2us) as request, and wait 0.5s for conversion, and then it sends back 3*16 bits(=48 bits, = 48 * 1/15 us = 3…

  • ADS7253: how to design anti-alias filter for INA240+ADS7253?

    TI Thinks Resolved
    Part Number: ADS7253 Hi, Here is a customer design using INA240 +ADS7253 as below. The sampling frequency is 10ksps, working common voltage is 48~72V. They found anti-alias filter(R30,R31,C17) influence the sampling performance a lot, sampling vibration…
