IDT ZSSC4165汽车传感器信号调理解决方案
IDT公司的ZSSC416x/ZSSC417x系列是用于高精度放大和差分桥传感器信号修正的CMOS集成电路,模拟放大范围从150到200,可调理所有的电阻桥和电压源类传感器如热电偶,失调,灵敏度,温漂和非线性数字补偿由16位RISC MCU来实现,而校准系数和配置数据存储在器件中的非易式存储器(NVM),具有SENT或I2C输出,主要用在汽车电子.本文介绍了ZSSC4165主要特性,框图,应用电路以及ZSSC416xKIT系列评估板主要特性和SSC通信板主要特性和优势与电路图.
IDT’s ZSSC416x/ZSSC417x is a family of CMOSintegrated circuits for highly accurate amplificationand sensor-specific correction of differential bridgesensor signals. Featuring a maximum analog pre-amplificationin the range of 150 to 200, this productis adjustable to nearly all resistive bridges as well asvoltage source sensor types; e.g.,thermocouples.
Digital compensation of offset, sensitivity, temperaturedrift, and nonlinearity is accomplished with a16-bit RISC microcontroller. Calibration coefficientsand configuration data are stored in the ZSSC416x/ZSSC417x non-volatile memory (NVM), which isreliable in automotive applications.
