ADC128S102QML-SP: About the /CS pin.

Tool/software:

Hello.

I am considering using a pull-down resistor to fix the /CS pin to low level. Will there be any problems with using it?

If there are no problems, how many ohms of pull-down resistor would be good? Please advise me.

Thanks and Regards,

Koji

    Hi Koji,

    /CS should not be pulled down since it idles high and is active low. /CS is usually not pulled high or low since controllers use push-pull transistors to drive the signal high and low. In some cases, this pin is pulled up. If you do choose to use a pull-up or pull-down resistor, a value of 10k ohms or beyond is common.

    Regards,
