__________________General Description

The MAX5352/MAX5353 combine a low-power, voltage-

output, 12-bit digital-to-analog converter (DAC) and a

precision output amplifier in an 8-pin µMAX or DIP pack-

age. The MAX5352 operates from a single +5V supply,

and the MAX5353 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 MAX5352/MAX5353 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 SPI™/QSPI™

and Microwire™. 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.
