ADuC847:精密模拟微控制器：12MIPS 8052 Flash MCU + 10通道24位ADC + 12位DAC
ADuC847/ADuC848 MicroConverter将24/16位多通道Σ-Δ型ADC和Flash微控制器完全集成在一个芯片上。这些器件针对要求精密采集多个（最多10个）通道的工业控制、智能传感器、称重传感器和仪器仪表应用进行了优化。ADuC847/ADuC848提供52引脚PQFP或56引脚CSP封装，采用3 V或5 V电源供电，额定温度最高为125ºC（CSP仅85ºC）。与ADI公司的所有MicroConverter产品一样，QuickStart和QuickStart-Plus系列开发工具也支持这些器件。
The ADuC847/ADuC848 MicroConverter products are fully integrated 24-Bit/16-Bit, Multi-Channel Sigma-Delta ADC and Flash Microcontroller on a single chip. These devices are optimized for applications in industrial control, smart sensors, loadcells and instrumentation that require precision acquisition of multiple (up to 10) channels.The ADuC847/ADuC848 are available is 52-pin PQFP or 56-pin CSP packages and operates on a 3 V or 5 V power supply and are specified up to 125ºC (CSP up to 85ºC only). Like all of ADI’s MicroConverter products, the device is supported by the QuickStart and QuickStart-Plus range of development tools.
