12-bit DA converter, 2.7 ... 5.5 V, I2C, SOT-23-6

12-Bit Voltage Output Digital-to-Analog Converter with EEPROM and I2C Interface

Description:
MCP4726 is a single channel, 12-bit, voltage output Digital-to-Analog Converter with integrated EEPROM and an I2C Compatible Serial Interface.
The MCP47X6 DAC family 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. These devices are available in small 6-pin SOT-23 and DFN 2x2 mm packages.
