Microchip Technology MCP4728 Quad DAC with EEPROM

Microchip Technology MCP4728 is the industry's first 12-bit Quad Digital-to-Analog Converter (DAC) to include non-volatile EEPROM, which allows the DAC´s configuration to be loaded automatically on start up. The non-volatile EEPROM gives designers the flexibility to program MCP4728 DAC input codes, configuration bits, and I2C address bits to the EEPROM using I2C serial-interface commands. This Microchip Technology Quad DAC holds its data during power-off time and its configuration and outputs are available immediately after power-up. The Microchip Technology MCP4728 also extends battery life by allowing each channel to be individually shut down, which can reduce power consumption to as low as 0.04 microamperes.
