MCP47DA1 is a volatile, 6-Bit digital Digital-to-Analog Converter (DAC) with a windowed output for server voltage margining applications. The MCP47DA1 has a windowed output (1/3 to 2/3 of VREF). The DAC setting is controlled through an I²C™Compatible serial interface. The I²C™Compatible slave addresses of “010 1110” and “011 1110” are supported.
