Hi

Please could you tell me exactly how to work out the voltage resolution per LSB of the 9361 RX channel ADC for the AD9361

We've made some assumptions and are not sure we are correct as the data sheet and reference manual do not provide enough details of this. The reference manual quotes "The ADC maximum input (0 dBFS) is 0.625 V peak". This to me tells me ac coupled the input and biased at 0.625V and the pk-pk is 1.25V??? We consider the ADC output 12-bits as -2047 to +2047??

Please could you give me the your calculations and parameters for ADC voltage resolution with a description on some of the parameters, e.g. input bias level, pk-pk, etc.

Kind Regards,

Andy

The ADC is 12 bits and its full scale input level is 1.25Vpk-pk.Your assumption on the output range is correct.

ADC is DC coupled and the part has DC correction calibrations that can be run to minimize DC offset.

The ADC provides approximately 60dB of dynamic range.
