Multi-output digital to analog converter

Abstract:

A circuit includes a first voltage divider having a set of most significant bit (MSB) outputs each representative of a value of a MSB portion of a digital code. The circuit also includes a second voltage divider having a first upper voltage input configured to couple to a first one of a first pair of outputs of the set of MSB outputs, and a first lower voltage input configured to couple to a second one of the first pair of outputs of the set of MSB outputs. The circuit also includes a third voltage divider having a second upper voltage input configured to couple to a first one of a second pair of outputs of the set of MSB outputs, and a second lower voltage input configured to couple to a second one of the second pair of outputs of the set of MSB outputs.
