PCM1808 16 bit data

Other Parts Discussed in Thread: PCM1808

Hi,

I want to use the pcm1808 for my ad conversions. This chip delivers 24-bit I²S data, but my microcontroller only supports 16-bit I²S data. Is it possible to use the pcm1808 for 16-bit resolution?

    Hi Wouter,

    It is not possible to limit the PCM1808 to 16 bit format. However, the way left-justified and I2S are done, the MSB is first and the LAB is alst. The difference between 24 bit and 16 bit are the 8 LSB bits. So if your microcontroller can take in the clocks for 24 bit, but only pay attention to the first 16 bits, then the audio should still work.
