Problem with one ADC SAR for multi-channel analog inputs
Software package: PSoC Creator 2.0
Hardware: CYBC55 Board
Schamatic design: a single ADC SAR component + an analog multiplexer component + multi-analog Pins.
The voltage value acquired from the ADC SAR is correct (Acquired voltage value = real world analog input voltage) when this design works on single analog input. However, the voltage values acquired from the ADC SAR are wrong (Acquired voltage values != real world analog input voltages) when work on multi-channel inputs.
Could you please advise me how to sort out this problem.
