ADS1278 Discrete date output mode

Other Parts Discussed in Thread: ADS1278

When I use the discrete date output mode to get the multiple channels AI. After the FSYNC signal pull high, it needs more than 2.5ms to read The Date ready signal DRDY. It's definitely too slow. I cannot find any information on show long it should be and wondering it is my code problem or just cannot use discrete output mode for fast data sample. Appreciated if anyone can help.

Thanks

    Hi Ken,

    Can you please clarify whether your are using SPI or FSYNC Mode? I ask because in FSYNC Mode, you should be providing the frame size and SCLKs when you wish to read data - there is no /DRDY pulse output from the ADS1278 to indicate when data is ready.

    Regards,
