Sensor Interface

Sensor interface ICs connect directly to a sensor element and provide the needed signal conditioning to extract an accurate signal for monitoring and control systems. Fully integrated sensor signal conditioners connect directly to the sensor, perform conditioning, and optionally fulfill data communication functions.
