SparkFun I2C DAC Breakout - MCP4725  (BOB-12918)新型號

Description:

     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!
     您一直想從微控制器輸出類比電壓，MCP4725 就是可以讓您做到這一點的 DAC！ MCP4725 是 I2C控制的數位類比轉換器 (DAC)。 DAC 可讓您從數位來源（例如Arduino 微控制器上的I 2 C 介面）發送類比訊號（例如正弦波） 。數位類比轉換器非常適合聲音生成、樂器和許多其他創意項目！

     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.
     此版本的 MCP4725 Breakout 修復了電路板的一些問題，包括 IC 佔用空間、I 2 C 引腳排列，改變了電路板的整體尺寸以更好地適合您的項目，並進行了一些細微的調整。此電路板分出了您需要存取和使用 MCP4725 的每個引腳，包括 GND 和訊號輸出引腳，用於連接示波器或您需要連接到電路板的任何其他裝置。板上還有 SCL、SDA、VCC 和另一個 GND，用於基本的 I 2 C 引腳排列。此外，如果您希望在總線上安裝多個 MCP4725，則可以停用此板上的上拉電阻，只需查看下面文件部分中的連接指南以取得執行此操作的說明和提示。
