__________________General Description
The MAX5354/MAX5355 combine a low-power, voltage-
output, 10-bit digital-to-analog converter (DAC) and a
precision output amplifier in an 8-pin µMAX or DIP pack-
age. The MAX5354 operates from a single +5V supply,
and the MAX5355 operates from a single +3.3V supply.
Both devices draw less than 280µA of supply current.
The output amplifier's inverting input is available to the
user, allowing specific gain configurations, remote
sensing, and high output current capability. This makes
the MAX5354/MAX5355 ideal for a wide range of appli-
cations, including industrial process control. Other fea-
tures include a software shutdown and power-on reset.
The serial interface is compatible with SPITM/QSPITM
and MicrowireTM. The DAC has a double-buffered input,
organized as an input register followed by a DAC regis-
ter. A 16-bit serial word loads data into the input regis-
ter. The DAC register can be updated independently or
simultaneously with the input register. All logic inputs
are TTL/CMOS-logic compatible and buffered with
Schmitt triggers to allow direct interfacing to opto-
couplers.

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.
