ADS124S06: ADS124S06 Read Data Direct setting

Masa Katayama

Part Number: ADS124S06

Dear Sir,

May I ask if the Read Data Direct mode does not need register setting?  It will be automatically entered in if DIN is kept low after /DRDY became low?

Best regards,

Masa

    Hi Masa-san,

    There is no register setting for the Read Data Direct mode as this is always enabled. This allows for a WREG command to be issued to change the mux setting the same time the conversion result is being read. If other commands are issued, such as RREG, the output will change from conversion data to register data after the command byte has decoded.

    As the data output is from an SPI slave device, a master will still need to send SCLKs to retrieve the data. This is usually initiated by transmitting a series of bytes as NOP (0x00) to the ADS124S06.

    Best regards,
