ADC0809是广泛使用的模／数转换器，在可不采用外部总线结构的单片机系统中(如 由AT89C51组成的系统)。ASC0809的数据线直接与单片结构的I／0 口相连，并由单片机的I／O 口直接对ADC0809进行控制。-ADC0809 is widely used in analog/digital converters, in not using the external bus architecture in the single-chip microcomputer system (such as the composition of the system by the AT89C51). ASC0809 data lines directly with the monolithic structure of I/0 I connected the MCU I/O port directly to control the ADC0809.
