ADS131A02: 10kohm resistor is used as pull up (or pull low) resistor for M0/M1/M2. What is possible risk?

hi,

My customer populated 10Kohm pull-up (or pull low )resistor for M0/M1/M2. They want to know what the possible risks?

Must pull-up/pull low resistors for M0/M1/M2 be < 1Kohm?

    Hi Ken,

    1-kohm or less value resistor is recommended in order to prevent the those pins from latching in a wrong state during ADC's power-up. These pins can be directly tied to the IOVDD supply or GND if the customer prefers. 

    BR,
