产品描述

模拟量输出是计算机或控制系统输出的模拟量，在单片机控制系统中，输出信号中模拟量为数不少，它们是单片机输出的数字信号经过模拟量输出通道处理后得到的。

模拟量输出通道的任务是把计算机处理后的数字量信号先通过数据总线、隔离装置，再通过D/A转换器转换成模拟电压或电流信号，经放大用以驱动相应的执行器，从而达到控制的目的。

Product description

Analog output is the analog output of computer or control system, in the single-chip microcomputer control system, there are many analog output signals, they are the digital signal output by the single-chip microcomputer after analog output channel processing.

The task of the analog output channel is to convert the digital signal processed by the computer into an analog voltage or current signal through the data bus, the isolation device, and then through the D/A converter, which is amplified to drive the corresponding actuator, so as to achieve the purpose of control.
