Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability

The MAX549 dual, serial 8-bit, voltage-output, digital-toanalog converter (DAC) operates on a single +2.5V to +5.5V supply. Its ±1LSB TUE specification is guaranteed over temperature. Operating current (supply current plus reference current) is typically 150A with V_DD = 2.5V and less than 1A in shutdown mode.

The MAX549 operates at clock rates up to 10MHz and is compatible with 3-wire SPI™, QSPI™, and Microwire™ interface standards. The serial input shift register is 16 bits: 8 bits for DAC selection and shutdown control, and 8 bits of DAC input data.

The MAX549's ultra-low power consumption and small MAX package make it ideal for portable and batterypowered
applications.
