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 con-
figurations 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.
The MAX5109 has independent high and low reference
inputs allowing maximum output voltage range flexibili-
ty. 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 sup-
ply and consumes 200A per DAC. A software-con-
trolled power-down mode decreases supply current to
less than 25A. A software-controlled mute mode sets
each DAC, or both DACs simultaneously, to their respec-
tive 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.
