Microchip Technology MCP4725 Digital-to-Analog Converter

Microchip MCP4725 Digital-to-Analog Converter is a single-channel, 12-bit, voltage output DAC with integrated EEPROM and an I2C Compatible Serial Interface. The MCP4725 DAC offers integrated non-volatile memory (EEPROM) which allows DAC register and  configuration bit values to be saves at powered off. The VREF pin or the device VDD can be selected as the DAC’s reference voltage. Power-Down modes enable system current reduction when the DAC output voltage is not required.    

The MCP4725 is offered in a compact 6-lead SOT-23 package, with an extended -40°C to +125°C operating temperature range.
