描述

 

您一直想從微控制器輸出模擬電壓,MCP4725是可以讓您做到這一點的DAC!MCP4725是一個I 2 C控制的數模轉換器(DAC)。DAC允許您從數字源(例如Arduino微控制器上的I 2 C接口)發送模擬信號(例如正弦波)。數模轉換器非常適合產生聲音,樂器和許多其他創意項目!

該版本的MCP4725 Breakout解決了電路板的一些問題,包括IC佔用面積,I 2 C引腳分佈,更改了電路板的整體尺寸以更好地適合您的項目以及其他一些小的調整。該評估板會分解您需要訪問的每個引腳,並使用MCP4725(包括GND和Signal OUT引腳)連接到示波器或您需要連接到評估板上的任何其他設備。板載SCL,SDA,VCC和用於基本I 2 C引腳的另一個GND 。此外,如果您要在總線上使用多個MCP4725,則可以禁用該板上的上拉電阻,只需查看以下文檔部分中的連接指南,以獲取有關說明和提示。

文件與函數庫

You’ve always wanted to output analog voltages from a microcontroller, the MCP4725 is the DAC that will let you do it! The MCP4725 is an I2C controlled Digital-to-Analog converter (DAC). A DAC allows you to send analog signal, such as a sine wave, from a digital source, such as the I2C interface on the Arduino microcontroller. Digital to analog converters are great for sound generation, musical instruments, and many other creative projects!

This version of the MCP4725 Breakout fixes a few issues with the board including the IC footprint, the I2C pinout, changes the overall board dimensions to better fit your projects, and a few more minor tweaks. This board breaks out each pin you will need to access and use the MCP4725 including GND and Signal OUT pins for connecting to an oscilloscope or any other device you need to hook up to the board. Also on board are SCL, SDA, VCC, and another GND for your basic I2C pinout. Additionally, if you are looking to have more than one MCP4725 on a bus, the pull-up resistors on this board can be disabled just check the Hookup Guide in the Documents section below for instructions and tips on doing this.
