ADS1018: SPI issue (DOUT)

Lee, Sam
Expert 5205 points
Part Number: ADS1018

Hi team,

Could you please look into an issue for DOUT level of ADS1018?

Problem: 

-. DOUT never goes to low level (0V).

-. The waveform keeps high even when isolating DOUT from MCU. 

Any check point?

CH1:CS / CH2:CLK / CH3:DOUT / CH4:DIN

Thanks,

Sam Lee

    Sam,

    I suspect that your DOUT line is shorted to something that is forcing it high.  You may want  to double check the soldering connections.  If you are using the VSSOP package can you de-solder DOUT pin, lift it, and measure the pin directly?  Otherwise, can you cut the trace near the pin and measure the pin directly.  

    Best regards,
