Abstract: The present invention is applicable to the field of communication, and provides an analog digital data conversion method, an analog digital data convertor and an analog digital conversion chip. The method includes: converting multiple groups of analog data to multiple groups of digital data; performing frequency shift on the multiple groups of digital data, wherein the multiple groups of frequency shifted digital data are independently distributed within a first preset bandwidth; filtering the multiple groups of frequency shifted digital data to remove outband information; and distributing without overlap the filtered multiple groups of digital data within a second preset bandwidth. The method substantially reduces pressure of data transmission between the converter and an FPGA or ASIC, and effectively simplifying the design of a multiband receiver.
