Abstract: A sensor package, and in one embodiment a sensor package for surface mount applications, that comprises a leadframe with an upper and lower surface for receiving a device thereon. Embodiments of the sensor package comprise a first device secured to the upper surface, and a second device secured to the lower surface so as to place connective pads from each of the first device and the second device proximate to one side of the leadframe. The sensor package further comprises a lead that is positioned in the sensor package in a manner that prevents electrical connection with circuitry that is external of the housing. The lead has an end proximate the side of the lead frame where the connective pads are positioned on the upper and lower surfaces. The end configured to receive connections, e.g., wirebonds, from the connective pads in a manner connecting the first device and the second device independent of any external connections of the sensor package.

Abstract: A surface mount package for a multi-chip device has a leadframe formed with first and second die pads and readouts from the respective die pads. An environmentally responsive sensor chip is secured to the first die pad and an environmentally isolated chip is secured to the second die pad. The chips are electrically coupled through the lead frame. A body formed with an over molded portion encases the isolated chip and an open molded portion formed with a recess receives the environmentally sensitive chip. An apertured cover is secured in the recess to form a protective covering over the sensor chip and for allowing communication of the sensor chip externally of the package.
