A magnetic field sensor package is disclosed. The package includes a substrate that has a front side and a back side opposite the front side. The substrate can comprise a lead frame. The package also includes a first magnetic field sensor die that is electrically and mechanically mounted on the front side of the substrate. The package also includes a second magnetic field sensor die that is electrically and mechanically mounted on the front side of the substrate. The package further includes a magnet that is disposed on the back side of the substrate. The magnet can provide a bias field for the first magnetic field sensor die and the second magnetic field sensor die. The package can also include a molding material that is disposed about the lead frame, the first magnetic field sensor die, the second magnetic field sensor die, and the magnet.
