Absolute and differential pressure sensors and related methods
Implementations of absolute pressure sensor devices may include a microelectromechanical system (MEMS) absolute pressure sensor coupled over a controller die. The MEMS absolute pressure sensor may be mechanically coupled to the controller die and may also be configured to electrically couple with the controller die. A perimeter of the controller die may be one of the same size and larger than a perimeter of the MEMS absolute pressure sensor. The controller die may be configured to electrically couple with a module through an electrical connector.
