The Elmos SSPs are suitable for numerous automotive applications. Pressure, torque and related physical parameters can be measured with resistive MEMS, ceramic or metal film measuring bridges. The ICs feature a broad adjustment range, straightforward calibration via a serial input/output (SIO) for the entire system and extensive configuration options. They also have comprehensive, integrated self-test functions and are highly robust against overvoltage, especially for automotive applications.
