ADI公司的ADuCM360是全集成的3.9 kSPS, 24位数据采集系统,包括有两个高性能多路Sigma-Delta (Σ-Δ) ADC,一个32位ARM Cortex™-M3处理器和闪存/EE存储器,可编程ADC输出速率(3.5 Hz - 3.906 kHz),50/60Hz噪音抑制,RMS噪音,3.53Hz时为52nV,50Hz为200nV,主要用在工业自动化和过程控制,智能精密传感系统,4mA-20mA智能传感器系统,医疗设备和病人监护.本文介绍了ADuCM360主要特性,功能框图,典型系统配置图,以及采用ARM Cortex-M3的14位4-20mA回路供电的热电偶温度测量系统的优势和特性,电路图和PCB元件图.
The ADuCM360 is a fully integrated, 3.9 kSPS, 24-bit data acquisition system that incorporates dual high performance, multichannel sigma-delta (Σ-Δ) analog-to-digital converters (ADCs), a 32-bit ARM Cortex™-M3 processor, and Flash/EE memory on a single chip. The ADuCM360 is designed for direct interfacing to external precision sensors in both wired and battery-powered applications. The ADuCM361 contains all the features of the ADuCM360 except that only one 24-bit Σ-Δ ADC (ADC1) is available.
