MCP4725 模組 I2C DAC Breakout 開發板 附排針
MCP4725是具有非易失性存儲器（EEPROM）的單通道12位緩衝電壓輸出DAC。 用戶可將配置寄存器位（2位）和DAC輸入數據（12位）存儲到非易失性EEPROM（14位）存儲器中。通過設置配置寄存器位可以把DAC配置成正常模式或節省功耗的關斷模式。 器件可以使用2線I2C兼容串行接口，且由電壓範圍為2.7V至5.5V的單電源供電。
Description: You’ve always wanted to output analog voltages from a microcontroller, the MCP4725 is the DAC that will let you do it! The CJMCU-MCP4725 is an I 2 C 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 I 2 C 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 CJMCU-MCP4725 Breakout fixes a few issues with the board including the IC footprint, the I 2 C 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 I 2 C 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.
- 12-bit resolution
- I 2 C Interface (Standard, Fast, and High-Speed supported)
