ADI ADUCM360数据采集系统解决方案
ADI公司的ADUCM360是24位数据采集系统解决方案,集成了两个多路24位Sigma-Delta ADC,32位ARM Cortex M3 MCU以及闪存/EE存储器,能直接和外部精密的传感器接口.单端和全差分输入,可编程ADC输出速率(4Hz到4kHz),同时对50Hz/60Hz抑制,主要用在工业自动化和过程控制,智能精密的传感器系统,4-20mA回路智能传感器系统,医疗设备和病人监护.本文介绍了ADuCM360主要特性, 方框图以及ADUCM360/361评估板主要特性,电路图和PCB布局图.
The ADuCM360 is a fully integrated, 4 kSPS, 24-bit data acquisition system incorporating dual, high performance multi-channel sigma-delta (Σ-Δ) analog-to-digital converters (ADCs), 32-bit ARM Cortex M3® MCU, and Flash/EE memory on a single chip. The part 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 the primary ADC, ADC0 is not available – only the auxiliary ADC, ADC1 is available.
The device contains an on-chip 32 KHz oscillator and an internal 16MHz high-frequency oscillator. This clock is routed through a programmable clock divider from which the MCU core clock operating frequency is generated. The maximum core clock speed is 16MHz and this is not limited by operating voltage or temperature.
