Nonvolatile, Quad, 8-Bit DACs
General Description
The MAX5105/MAX5106 nonvolatile, quad, 8-bit digital-
to-analog converters (DACs) operate from a single
+2.7V to +5.5V supply. An internal EEPROM stores the
DAC states even after power is removed. Data from
these nonvolatile registers automatically initialize the
DAC outputs and operating states during power-up.
Precision internal buffers swing Rail-to-Rail®, and the
reference input range includes both ground and the
positive rail.
The MAX5105/MAX5106 feature a software-controlled
10µA shutdown mode and a mute state that drives the
DAC outputs to their respective REFL_ voltages. The
MAX5105 includes an asynchronous MUTE input, as
well as a RDY/BSY output that indicates the status of
the nonvolatile memory.
The MAX5105 is available in a 20-pin QSOP and 20-pin
wide SO packages, and the MAX5106 is available in a
16-pin QSOP package.

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.
