    Is code generated for the AD1450 compatible with the ADAU1451 and ADAU1452.. The design utilizes the ADAU1450. But for second sourcing considerations , can the ADAU1451 and ADAU1452  be substituted without any code changes?

        The 1463/1467 aren't pin-compatible, they come in an 88-pin package rather than the 72-pin package of the 145x/1462/1466.
        
 
        Compatible upgrade paths are (as far as I know):
        
 
        1450 → 1451 → 1452
        
 
        1450 → 1462-150 → 1462-300 → 1466
        
 
        1451 → 1462-300 → 1466
        
 
        1452 → 1462-300 is not quite compatible since it seems the 1462 splits each DM into two pages of 12Kwords for slave port access, rather than having 24Kwords contiguous (even though 24Kwords contiguous would have fit in the slave port address space, so paging shouldn't have been necessary).
