传统上,在同一颗芯片上提供 ADC和 D A C 支持是混合信号微控制器所应达到的最低要求,然而设计人员对于所谓“混合信号”组件的期望却更高。真正的混合信号微控制器是一种系统单芯片,它能同时处理模拟和数字的输入与输出,效率则不输给分立解决方案。虽然只有少数产品算是功能完 Traditionally, providing ADC and DCAC support on the same chip was a minimum requirement for mixed-signal microcontrollers, but designers are expecting even more for so-called “mixed-signal” components. A true mixed-signal microcontroller is a system-on-a-chip that can handle both analog and digital inputs and outputs at the same time without losing efficiency to discrete solutions. Although only a few products count as functional end
