This document describes the requirements and design challenges of automotive sensors, and the solutions provided by ADI. Their products include pressure sensors, current sensors, capacitance sensors, position sensors, speed sensors, and temperature sensors.
This document introduces Analog Devices' (ADI) solutions for automotive sensor and sensor interface applications. It addresses the challenges of improving fuel economy and reducing emissions by enhancing combustion sensing and control performance. The text categorizes vehicle sensors into six functional groups: pressure, current, capacitive, position, velocity, and temperature sensors. This manual is written in Chinese.
| Pressure Sensor Temperature Range | -40°C to +125°C |
|---|---|
| Pressure Sensor Max Pressure | 2,800 bar |
| Current Sensor Bandwidth | 500 kHz |
| Current Sensor Common Mode Voltage | 65 V |
| Capacitive Sensor Resolution | High |
| Position Sensor Accuracy | 0.1° |
| Temperature Sensor Accuracy (TMP36) | ±2°C |
| Temperature Sensor Accuracy (ADT7311/ADT7312) | ±1°C |
| Temperature Sensor Range (ADT7312) | -40°C to +175°C |
| Resolution Digital Converter (AD7745/AD7746) | 24-bit |
Vehicle sensors are typically categorized into six functional groups: pressure, current, capacitive, position, velocity, and temperature sensors.
The typical operating temperature range for pressure sensors is from -40°C to +125°C, though it can reach up to 150°C in some cases.
ADI's strain gauge signal conditioning chips include AD8556, AD8557, and the new generation ADA4556.
The ADT7311 and ADT7312 temperature sensors achieve an accuracy of ±1°C over their full scale range.
