Part Number: PCM1820
Other Parts Discussed in Thread: PCM1861,

Hello,

We are proposing PCM1820 as a successor of existing PCM1861, however we need an analog front-end mux function.

Could you kindly let us know if PCM1820 build in an analog front end mux or similar function.

Best regards,

The PCM1820 Inputs direct drive 2 individual ADC's.There is no Mux.

What specific functionality do you need from the mux?

Thank you for your feedback. I understood that PCM1820 does not build in analog front end mux function.

Our customer does not use the mux in the customer own way of use but just use as switching analog input path, same as what PCM1861 described in the datasheet.

Best regards,
