Functionally, these parts are identical. The differences are in the sizes of the program and data RAMs. The ADAU1701 has 1024 instructions/cycle in the program RAM and 2k words of data memory, while the ADAU1702 has 512 instructions/cycle and 0.5k words of data memory. The ADAU1401 has the same specs as the ADAU1701, but is qualified over the automotive temperature range.
