DAC Breakout - MCP4725 module development board

The MCP4725 is a single-channel 12-bit buffered voltage output DAC with non-volatile memory (EEPROM). The user can store the configuration register bits (2 bits) and DAC input data (12 bits) to non-volatile EEPROM (14 bits) memory. The DAC can be configured in normal mode or power-saving off mode by setting the configuration register bit. The device can use a 2-wire I2C compatible serial interface and is powered by a single supply with a voltage range of 2.7V to 5.5V.

Description: Youve 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 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 CJMCU-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.

Features:

12-bit resolution

Internal EEPROM to store settings

Introduction to the MCP4725 module

Single channel (1 DA output)

12-bit resolution

I2C interface (Standard, fast, high-speed support)

2.7V to 55V supply voltage

Internal EEPROM storage Settings

12C address configurable (A0) (A1, A2 built-in, default to '00')

Address of the MCP4725 module

The default device address inside the chip starts with 1100', the drop down inside A2 and A1 is' 00', and A0 is '0' by default, so the device address is 0x60 by default.

If two 4725 modules are used at the same time, the A0 of one module can be changed to pull-up processing, and the change position is shown in the following figure. If the solder is changed to ADDR connected to VCC, the device ground is 0x61.
