Other Parts Discussed in Thread: OPA320, OPA350
I use the differential 16-bit-ADC of a F28377S with 2.5V-Reference and two different CCS-project-configurations: RAM (RAM only) and FLASH (stored in FLASH, signal processing executed from RAM).
The RAM-only version shows a better noise performance (approx. 100 uV RMS, 8 LSB peak/peak), the FLASH-version is worse (approx. 200 uV RMS, 16 LSBt peak/peak).
In the FLASH-version there are still some functions executed in the flash. Does it affect the ADC-performance?
