接口 IC

The Allegro A6850 is an interface integrated circuit (IC) that provides the sensor output state and diagnostic data (open and short status) between two-wire current output sensor ICs and a microcontroller.

AN296244 - This paper provides an overview of the general format of a SENT message and explains how the Allegro A17700 pressure interface sensor can be configured to use SENT to communicate pressure, temperature, and other useful application specific information.

As the demand for energy-efficient systems continues to rise, so does the need for pressure regulation in liquid and gas carrier systems. Allegro’s A17700 is a highly accurate interface IC that incorporates a top-of-the-line signal conditioning algorithm designed for resistive bridge pressure sensors.

AN296197 - This application note aims at providing a complete example of calibration using A17700 Pressure Sensor Interface.

AN296202 - This application note explains the science behind the strain gauge used for pressure sensing, most common strain gauges on the market, sensing solutions presented by different strain gauge configurations, and A17700 input specifications.
