D/A board 簡單說就是 Digital to Analog 板子, 它是一些 D/A 轉換器加上一個傳輸介面像 PCI, PCMCIA, USB, etc。 讓個人電腦或儀器設備可以將數位信號轉換成類比電壓/電流來控制或產生相對動作。
比方將轉速上 PWM 轉換成電壓電流來控制馬達
跟他相對的是 A/D board, 底下是 A/D board的解釋
First, A/D is an abbreviation for analog to digital. Therefore, an A/D board is a basic analog-to-digital converter coupled with an interface that allows a personal computer to control the actions of the board, as well as to capture the digital output information from the converter. These boards are designed to plug directly into a personal computer's bus. All the power required for the A/D converter and associated interface components is obtained directly from the PC bus.
