Aux ADC Input
Click here to return to the Inputs and Outputs Toolbox page.
The Auxiliary ADC Input algorithm takes the digital signal from the auxiliary A/D (analog-to-digital converter) and makes it available in the design.
Note: This block is only available for use with DSPs that have auxiliary ADC (e.g. ADAU1701).
Use the block's drop-down list control to select from the available ADC inputs.
Every enabled input must be connected to an output, else there will be errors on compilation.
Observe that as you drag more ADC input blocks into the schematic, the number of auxiliary ADCs available in the drop-down decreases because they can only be represented by one block at a time.
To change the Sampling Rate for an Aux ADC Input, Right-click the block name and select Set Sampling Rate, which brings up the Sampling Rate window (default is 44.1 kHz
