Single-Supply 3V/5V, Voltage-Output, Dual,
Precision 10-Bit DACs
General Description
The MAX5236/MAX5237 precision, dual, voltage-out-
put, 10-bit digital-to-analog converters (DACs) con-
sume only 360µA from a single 5V (MAX5237) or 325µA
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
register loads data into the input registers. Input regis-
ters update the DAC registers independently or simulta-
neously. In addition, programmable control bits allow
power-down with 1kΩ or 200kΩ 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 µMAX packages.
