XINGYHENG 5Pcs MCP4725 Breakout Module I2C DAC Development Board 2.7V to 5.5V Supply
About us:
MCP4725 is a single channel 12 bit buffer voltage output DAC with non-volatile memory.The user can store configuration register bits (2-bit) and DAC input data (12-bit) into non-volatile (14-bit) memory. The DAC can be configured to 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 power source with a voltage range of 2.7v to 5.5v
Features
- 12-bit resolution
- I2C Interface (Standard, Fast, and High-Speed supported)
- Small package
- 2.7V to 5.5V supply
- Internal to store settings
Module performance and features:
- 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 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.

It works but with two serious issues that will keep me from buying again:1. There is no A0 pin to change the I2C address. This greatly complicates things if you need to write to multiple MCP4725s from a single microprocessor.2. There is no documentation with even the most basic and essential information. Like the I2C DEFAULT ADDRESS. Unbelievable. So you have to run your own experiments to figure out which address to use.100% do not recommend.There is no excuse for a manufacturer to omit critical detail about the product they sell. Users will need to know the default address of this device. Where is that info? Are we suppose to guess, or to morph into detectives in order to get started with this thing? The Adafruit MCP4725 clearly identifies the default address RIGHT ON THE CHIP. Borrow a page from their book and do the same? Grief.

These met my expectation and perhaps a bit more. I was looking for a cheap 12b DAC for micros that didn't have one built in and the 4725 fit the bill. They came with no documentation but the MCP4725 is widely used and documentation easily obtained. When I finally got around to trying it out, Sparkfun's website got me going in about 15min. I was pleased with the 5vpp output. The device only has a single address pin which could be tied high or low for address 0x61 or 0x60, or it could be used as a high or low chip select in case one needed more than two DACs.

I used one of these to drive the contrast adjustment for an LCD on an Arduino-based project.A couple of points: -- At first I used a specific library to drive the device, but I found it easy enough to write my own functions in conjunction with the Arduino Wire library- 0x60 was the address I had to use.The non-volatile write option is handy; e.g. in my case I can allow the user to adjust the display, then set the output until it needs to be changed again.

All five worked flawlessly. Interfacing with a Teensy and Arduino. Also worked with Adafruit’s multiplexer.

I have purchased probably 20 of these and haven't had a problem with any of them
