ADS1298R: ADS1294R SPI issue

Part Number: ADS1298R
Other Parts Discussed in Thread: ADS1294R

Dear all,

We designed board with the ADS1294R and we have issue with the SPI. We have no ID returned and the value retuned is completely different we should hve (should have 0x60).

The ADS1294R reset pin is driven by an external MCU so the chip is well reset. we are using internal clock and configuration of the ADS1294R is on unipolar mode (3V3 for AVDD and DVDD, AVSS=GND)

Do you have any idea?

Thanks

Regards,

Damien
