Other Parts Discussed in Thread: ADS1299, ADS1278
I want to use two ADS1292 synchronously. Right now, I am doing the PCB layout and I have strict requirements on the PCB size and number of layers. I am looking for ways to simplify the connections between the two ADS1292 and microcontroller.
For this I have two ideas:
- Can I share the CLK and SCLK signal?
- Can I use only one DRDY (since the two ADS1292 are synchronized (shared START pin and CLK) then the new data should always be available at the same time)? I have read in this forum that the DRDY pins of several ADS1292 cannot be connected together, but instead I could connect the first ADS1292 DRDY pin to the microprocessor and leave the second ADS1292 DRDY pin floating, right?
