ADS1274 DRDY signal pull down 4.7K resistor is ok?
Hello,
When operating in the mode with /DRDY as an output, is a push-pull output, so you don't need any pull-ups or downs. That said, if you're okay driving extra current out the /DRDY pin (Voh/4.7k), then there shouldn't be any issues putting the pull-down there. The digital outputs specify the Voh levels with a 4mA output current.
