The MAX5109 dual 8-bit digital-to-analog converters (DACs) feature nonvolatile registers. These nonvolatile registers store the DAC operating modes and output states, allowing the DACs to initialize to specified configurations at power-up. Precision on-chip output buffers swing rail-to-rail, and provide 8s settling time. The I2C*-compatible, 2-wire serial interface allows for a maximum clock frequency of 400kHz.
