ADS1292R: CLK and GPIO Pin Connections

Other Parts Discussed in Thread: ADS1292R

Hi,

I want to ask question about connectiong of GPIO1 and GPIO2 pins to DGND. It is said in pdf of ADS1292R to connect these pin to DGND by series of resistor and I'll be thankfull if you have any idea about the value of these resistors. Also I want to ask question about CLK pin so the question is: where iI kave to connect the CLK pin if I want to use the internal oscillator of ADS1292R?

Thanks in advance!

Hello Ersin,

Thanks for your post and welcome to our forum!

The GPIO pins can be connected to DGND through a 10k resistor to DGND.

The CLK pin can be left floating when using the internal oscillator. If you want to share the internal CLK signal with other ADS129x devices, you can set CONFIG2[3] to enable the oscillator output.

Best Regards,
