MCP4725

MCP4725 is a single channel, 12-bit, voltage output Digital-to-Analog Converter 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. These devices are available in small 6-pin SOT-23 packages.

Digital Controlled Bench Power Supply
