What is tCONVERT (conversion time) for the SD24_B in the MSP430F6736? I see this specified for the 10-Bit ADC but not for the 24-Bit Sigma-Delta ADC.
I searched through our datasheets, and I had no success finding any sigma-delta ADC conversion time for any of these peripherals:
- SD14
- SD16_A
- SD24
- SD24_A
- SD24_B
When I try to calculate the conversion time myself, I get 3.2 ms, which seems long. I would like someone to verify my calculations (no longer attached. Updated version in later post).
If SMCLK is used for the SD24_B, does this mean I cannot use LPM3 during the conversion time?
