I'm using AIN port as ADC. I believe I should be able to read up to 1.35V since the reference voltage of ADC is VDD_AUX(=1.35V). I, however, actually couldn't read 1.35V. The maximum volatage that the CSR1011 can convert is 1.29V - 1.32V, depending of the sample.
Can someone advice why I couldn't convert up to 1.35V?
Thanks,
Is this on a Qualcomm development platform? If yes, please list which one. If not, can you share what is connected? Have you tried a constant power source for verification?
