I was given this sentence:

ここが、きみの クラスだから。

The explanation I was given is that the から at the end is used when giving
information. What is the だ used for? What are other examples of だから usage?

Clarifying だから use at the end of a sentence
「から」 used to indicate a cause or reason must follow a verb or adjective. 「だ」
is the copula 「である」, which binds the noun it follows with the causative
particle「で」 and the existence/possession verb 「ある」 in order to turn the noun
into a verb clause.

answer
`A から B` means 'B because A', and here, the B part is omitted, expecting the
addressee to reconstruct it. See [my answer to a related
question](https://japanese.stackexchange.com/questions/4022).

`だ` is the copula, and is here because the because-clause ends with a noun.
Depending on the type of the predicate, there are different endings.

> 君がクラスに来たから。 [verb]  
>  ここは寒いから。 [i-adjective]  
>  ここは静かだから。 [na-adjective]  
>  ここが君のクラスだから。 [noun]
