#184515 - Go for ADC with multiplexed inputs instead of multiple ADC Responding to: ???'s previous message |
Low or high quantity - I would recommend a single ADC with multiplexed inputs.
It will normally give less variance between the multiplexed inputs, that multiple ADC does. Remember that multiple ADC requires you to connect your single voltage reference to all ADC in a noise-free manner. Next thing is that a single ADC means that you have a single set of errors from nonlinearity, and non-uniform step sizes. With multiple ADC, they can have different characteristics. |
