  • ADS131M02: ADS131M02 skips CRC frame arbitrarily

    Resolved
    Part Number: ADS131M02 When issuing a register read command via SPI, the chip sometimes replies as expected, but sometimes skips the CRC frame. This means the response doesn't arrive at the expected frame. Is this behaviour known and expected? Here…
