مبدل دیجیتال به آنالوگ 12 بیتی MCP4725 دارای EEPROM داخلی

DAC Breakout - MCP4725 Module Development Board
The MCP4725  is a single-channel 12-bit buffered voltage output DAC with nonvolatile memory           ( EEPROM ) . The user can store the configuration register bits ( 2 bits) and the DAC input data           ( 12 bits) in the nonvolatile EEPROM ( 14  -bit) memory. By setting the configuration register bits, the  DAC  can be configured in either normal mode or power-saving shutdown mode.   The device can use a  2-  wire  I2C-  compatible serial interface and is powered from a single supply with a voltage range of 2.7V  to  5.5V  .
 
Description:  You've always wanted to output waveform voltages from a microcontroller, the MCP4725 is the DAC that will let you do it! The CJMCU-MCP4725 is an I2C controlled Digital-to-Analog converter (DAC) 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!
