General Description

The MAX5236/MAX5237 precision, dual, voltage-out-

put, 10-bit digital-to-analog converters (DACs) con-

sume only 360A from a single 5V (MAX5237) or 325A

from a single 3V (MAX5236) supply. These devices fea-

ture output buffers that swing Rail-to-Rail. The internal

gain amplifiers (1.6384V/V) maximize the dynamic

range of the DAC output.

The MAX5236/MAX5237 feature 13.5MHz a 3-wire seri-

al interface compatible with SPI/QSPI/and

MICROWIRE. Each DAC input is organized as an

input register followed by a DAC register. A 16-bit shift

ters update the DAC registers independently or simulta-

neously. In addition, programmable control bits allow

power-down with 1k

or 200k internal loads.

The MAX5236/MAX5237 are fully specified over the

extended industrial temperature range (-40°C to +85°C)

and are available in space-saving 10-pin MAX packages.
