Part Number: ADS112U04

Hello experts,

I have question about TX/RX/DRDY pins.
Do these pin have internal pull-up resistor?

Thanks and best regards,

    Hello Ryo,

    The pins do not appear to have an internal pull-up resistance.  Datasheet and EVM connections show direct connections to the host processor with some small ~47◙ series resistance to help with overshoot/ringing and protection.
