Other Parts Discussed in Thread: TIDA-01471,
I have any questions.
1. Please tell me the reason why R2, R3 and R4 described in "Schematic" of TIDA-01471 are connected.
If the reason for this is a damping resistor, please tell me the reason why it is connected to the input side of ADS127L01 (SCLK and DIN, ADC_CS) instead of the output side of the IC.
2. R2 = R3 = R4 = 499Ω, but please tell me the reason why the value is larger than 50Ω.
3. Is it correct to recognize that the role of the capacitor (C18) connected to SCLK is noise suppression?
