MCP4725DM-PTPLS

The MCP4725DM-PTPLS is a daughter board that demonstrates the MCP4725 features using Explorer 16 Development Board and PICkitTM Serial Analyzer. The MCP4725 is a low power, high accuracy, single channel, 12bit buffered voltage output Digital to Analog Convertor with Non-volatile memory (EEPROM). The DAC input and configuration data can be programmed to Non-volatile memory (EEPROM) by user using I2C interface command. The Non-volatile memory feature enables the DAC device to hold DAC input code during power off time, and the DAC output is available immediately after power up which is very useful when used as supporting device for other devices in network. The board has test points for SDL, SDA, and VOUT. By connecting an oscilloscope to these test points or Digital Multimeter to VOUT, the user can examine the data communications through the I2C bus line and observe resulting DAC output.
