Other Parts Discussed in Thread: MSP-TS430PZ100A, MSP430F47176
I am trying to obtain accurate SD16_A conversion results.
I conneted pins to reduce noise according to User's Guide of MSP430.
-----------------
1. PC-01 posotive -> A2.0 positive
2. PC-01 negative -> GND (J5 pin of MSP-TS430PZ100A)
3. V_REF -> capacitor 103 -> AVss
4. A2.0 negative -> AVss
5. AVcc -> capacitor 104 -> AVss
6. DVcc -> capacitor 104 -> DVss
-----------------
PC-01 is a portable calibrator to generate constant voltage (e.g., 500mV).
I use MSP430F47176. I use OSR_64.
Should I connect negative input (PC-01 negative) to AVss not to GND? Is this
cause some difference in the noise of the SD16_A conversion?
