MAX5109 - 8-Bit DACs

General Description

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.

19-3585; Rev 0; 2/05 www.DataSheet4U.com Nonvolatile, Dual, 8-Bit DACs with 2-Wire Serial Interface General Description 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 8µs settling time. The I2C*-compatible, 2-wire serial interface allows for a maximum clock frequency of 400kHz. The MAX5109 has independent high and low reference inputs allowing maximum output voltage range flexibility. The reference rails accept voltage inputs that range from ground to the positive supply rail. This device operates from a single +2.7V to +5.
