How to close channel of ADAU1979

ZhouAdi over 1 year ago

Hi!

I'm using ADAU1979 as ADC, it has 4 channels but I only needs 2 right now.

I have an array to store the data from ADAU1979 and the data of 4 channels are interleaved

I want to disable other 3 channels so I all my data is come from the only one channel

I tried the API adi_adau1979_ClipChannel and adi_adau1979_MuteChannel but find they didn't work

Is there any other solution to this?

Best Regards!

Hi,

The ADC's can be individually MUTED using the 0x0A thru 0x0D registers. However if you do not want that ADC output at all then you could try Register 0x04 ADC_ENx bits and disable the desired ones…
