Dual-Bridge Sensor Signal Processor with SENT Interface | E520.47

This IC provides low-noise sensor signal conditioning with two individual 15-bit Delta-Sigma ADCs for two resistive bridge sensors, including compensation and linearization. Two additional temperature channels with a 14-bit Delta-Sigma ADC allow for precise acquisition and linearization of divers temperature sensors. Internal sensor- and self-diagnosis, particular safety requirements and the development compliant to ISO26262 enable the integration of this IC into safety applications. All compensated and linearized sensor data are available at the digital SENT interface output. The dual function SENT pin permits a serial I/O communication to enable real 3-wire end-of-line configuration and calibration. Alternatively an additional I2C interface allows faster access to sensor, diagnosis, calibration and configuration data. A calibration tool set including a bench top evaluation software is provided to facilitate sensor mass production.
