AWR1843: Effective number of bits of ADC

Geogia

Part Number: AWR1843

Hi,

I'm using 1843 and 2944. As SDK userguide states, the numADCBits can only be set to 16bit. So what are the effective number of bits?

I want to confirm the range of the ADC data acquired by the 1843 and 2944.

Thanks in advance.

thank you

Hi Cesar, many thanks for your reply. I want to confirm with you that the ADC data is interpolated from 12bit to 16bit? If yes, what is the method of interpolating from 12bit to 16bit？

Hi,

16 bits are generated by the ADC. in order to convert to 12 bits, the 4LSBs are removed

thank you
