  • ADS8528: tcclk and BUSY signal about ADS8528

    Resolved
    Part Number: ADS8528 Hi All, I am using the ADS8528. In my design I have tied the CONVST of ABCD channels together. From the description in section 9.3.1.6, it says the BUSY output transitions low for a single conversion clock cycle(tcclk) whenever a pair…

    TI Thinks Resolved
    Part Number: ADS8528 We’ve been using ADS8528 in some of our projects, and I have a couple of questions about it. Where are the conversion results for each channel pair stored? Is there a way to access the conversion results for each channel pair…

  • ADS8528: Data output error

    TI Thinks Resolved
    Part Number: ADS8528 I am using the ADS8528 in HW configuration mode with internal ref 2.5 (x2) and with serial output. All 8 channels have inputs (see schematic) When reading the output data - there appears to be a random influence on other channels…

  • ADS8528: Enabling the internal reference buffer

    TI Thinks Resolved
    Part Number: ADS8528 Hi team, Is the only buffer that becomes Enable when /REFBUFEN (pin 20) is set Low the buffer after the StringDAC in the block diagram in 9.2? If an external reference is used, does /REFBUFEN (pin 20) need to be HIGH? Sincerely. Ry…
