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.
25V supply and consumes 200µA per DAC.
A software-controlled power-down mode decreases supply current to less than 25µA.
A software-controlled mute mode sets each DAC, or both DACs simultaneously, to their respective REFL_ voltages.
The MAX5109 also includes an asynchronous MUTE input, that drives both DAC outputs simultaneously to their respective REFL_ voltages.
The MAX5109 is available in a 16-pin QSOP and is specified for operation over the extended (-40°C to +85°C) temperature range.
