MCP4728 - Microchip Technology

MCP4728 Quad Digital-to-Analog Converter

The MCP4728 device is a quad, 12-bit voltage output Digital-to-Analog Convertor (DAC) with nonvolatile memory (EEPROM). Its on-board precision output amplifier allows it to achieve rail-to-rail analog output swing. The DAC input codes, device configuration bits, and I2C address bits are programmable to the nonvolatile memory (EEPROM) by using I2C serial inte.
