ADAU1701 has four 8-bit Auxiliary ADCs. I need to feed audio input (8-bit resolution is OK) through one of the four Auxiliary ADCs and route it to a 24-bit DAC.
How is the data format handled in this case? Is 8-bit data from Aux ADC filled up in lower 8 bits of 24-bit DAC, with upper 16 bits set to zeros?
Is there a SigmaStudio block that can handle the above data type conversion?
Can I use a gain block to multiply the 8-bit Aux ADC data so that it fits in the upper 8 bits of 24-bit DAC?
