ALPS Develops and Commences Mass Production of “HSPPAD Series” Digital Pressure Sensor
Single-Package Sensor with Temperature Compensation Function
Munich, Germany, April 25, 2014 – ALPS ELECTRIC EUROPE GmbH has developed the “HSPPAD Series” Digital Pressure Sensor, ideal for embedding in smartphones and other mobile devices. Mass production commenced in April 2014.

Today’s mobile devices and home appliances contain a large number of sensors. Used, for example, to detect the status of doors and lids, as well as environmental characteristics such as direction, illumination, air pressure and humidity, sensors enhance device functionality and performance and create comfortable and convenient operating environments for users.

To ensure accurate sensing of air pressure and humidity, the obtained data must be corrected according to the temperature of the surrounding environment. This temperature compensation is conventionally performed within the circuitry of the main unit, however, and simply incorporating a sensor device into the unit has not always resulted in accurate detection.

Drawing on market experience with the analog HSPPA Series, 350 million units of which have been produced to date, ALPS has now developed the HSPPAD Series pressure sensor with digital output. Mass production is already underway.

The HSPPAD Series has a built-in temperature compensation function, optimized based on data accumulated by ALPS through compensation simulations. This simultaneously removes the need to incorporate temperature compensation circuitry into the main unit and eliminates the power requirement for temperature compensation, contributing to energy savings.  

The product also achieves low-noise output with the configuration of the entire sensor, including the detection mechanism, having been optimized through the application of process and simulation technologies established through hard disk drive (HDD) business. This helps to reduce the signal averaging workload of the main unit. Furthermore, the sensor has a wide measurement range of 300 to 1,100hPa.
