ADS1191: How to read the data of ADS1191

Robin Zhou

Part Number: ADS1191


Dear TI Experts,

Is the ADS1191 read directly on the bus? Is it a register without data? Please help check~

Thanks,

Robin

    Hi Robin,

    The data output and data retrieval sections of datasheet covers this. 

    "The number of bits in the data output depends on the number of channels and the number of bits per channel. For the ADS1191/2, the number of data outputs is (16 status bits + 16 bits × 2 channels) = 48 bits. The format of the 16 status bits is (1100 + LOFF_STAT[4:0] + GPIO[1:0] + 5 zeros). The data format for each channel data are twos complement and MSB first. When channels are powered down using the user register setting, the corresponding channel output is set to '0'. However, the sequence of channel outputs remains the same."
