Other Parts Discussed in Thread: ADS1298
I have a question about SPI SCLK while using ADS1294.
SCLK PERIOD 66.6 ns (MAX 15 MHz) on DATASHEET, but if it actually works, it is fine from 1 to 5 MHz, but data corruption from 6 MHz will occur (using DVD 1.8 V).
On the PCB, the MASTER is connected directly to the series resistance of 33 ohms.
Resolution 24bit, sampling rate 250SPS in use.
1. We would like to ask if the maximum available frequency changes depending on the resolution and sampling rate.
2. Please check if it is right to use at least 61 kHz at resolution 24bit, sampling rate 250SPS.
3. I'd like to know what criteria the Tsclk of datasheet was measured based on.
