Hi,
Sinc filter can be inplemented without considering overflow, if you have reserved addition bit width for word length growth. Certaintly, The integrator can make a number overflow, but research papers state that the result is right though overflow occurs. Pelease refer to basic materials about cic filters.
Reguards,

Hi,
multibit and single bit does not impact the choice of filter. Multibit may impact your implementation of the filter. You may choose longer word length to preserve the precision of the filter.
Good luck
