传感器信号处理器IC

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.
