该A1342是一个特别可配置和最苛刻的线性领域传感器应用稳健的解决方案。BiCMOS单片集成电路包括霍尔传感元件、降低霍尔元件固有灵敏度和偏移漂移的精密温度补偿电路、小信号高增益放大器、专有动态偏移消除电路亚博尊贵会员、高级输出线性化电路和高级诊断。A1342提供了无与伦比的客户可编程选项水平。
A1342的一个关键特性是它能够为非线性输入磁场产生高度线性的设备输出。为了实现这一点，该设备具有16段客户可编程线性化，其中一个独特的线性化系数系数适用于每一段。线性化系数存储在EEPROM的查找表中。
The A1342 has two configurable output options: SENT or PWM. In addition to SAEJ2716, the A1342 includes two additional proprietary SENT options: SSENT and ASENT. Both protocols enable bus configurations with up to four devices on one SENT line to reduce system costs. SSENT provides sequential access to the sensors connected to the same line. SSENT provides a very low overhead method to maximize the sensor bandwidth on this single SENT line, minimizing impact on system performance. ASENT provides random access to all the sensors on the common SENT line. Both protocols allow individual sensors on the same line to enter diagnostic mode while the other sensors continue to respond to queries, allowing for the highest diagnostic coverage while maintaining 100% availability of the sensor solution.
