The short answer is "not necessarily, but very much usually".

DSA involves doing some complicated math on a 160-bit value. There's no
hard requirement the value be generated by SHA-1, and GnuPG/PGP 5+
provides RIPEMD160 as an alternative, but in reality hardly anyone uses
RIPEMD160.

This should not be confused with DSS, the Digital Signature *Standard*,
which specifies DSA with SHA-1 (and only SHA-1).
