The basic product concept of the VTI ADP is a two chip solution consisting of a single sensing element and one ASIC inside a pre-molded 12-pin housing. The interface to the application is a four wire digital SPI interface. In single axis products there is also a Pulse Width Modulation output available. In addition to the supply voltage filtering, the accelerometer does not require any other external components. The new family offers acceleration and inclination sensing as a complete platform, which can have the same pin-out in 1-, 2-, and 3-axis accelerometers. Measurements in X-, Y- and Z -direction as well as any combination of two and three directions are possible.
