Compact digital-to-analog converter

A digital-to-analog converter is disclosed. An example digital-to-analog converter circuit includes a reference scaling circuit coupled to receive a first reference current. The reference scaling circuit is coupled to generate a second reference current in response to the first reference current. The digital-to-analog converter circuit also includes a first plurality of binary-weighted current sources coupled to a summing node. A current of a first one of the first plurality of binary-weighted current sources is proportional to the first reference current. The digital-to-analog converter circuit also includes a second plurality of binary-weighted current sources coupled to the summing node. A current of a first one of the second plurality of binary-weighted current sources is proportional to the second reference current.
