10-Bit, Low-Power, Rail-to-Rail
Voltage-Output Serial DAC in SOT23
General Description
The MAX5711 is a small footprint, low-power, 10-bit digi-
tal-to-analog converter (DAC) that operates from a single
+2.7V to +5.5V supply. The MAX5711 on-chip precision
output amplifier provides Rail-to-Rail
®
output swing.
Drawing an 85µA supply current at 3V, the MAX5711 is
ideally suited to portable battery-operated equipment.
The MAX5711 utilizes a 3-wire serial interface compatible
with SPI™/QSPI™/MICROWIRE™ and DSP-interface
standards. All logic inputs are CMOS-logic compatible
and buffered with Schmitt triggers to allow direct interfac-
ing to optocouplers. The MAX5711 incorporates a power-
on reset (POR) circuit that ensures that the DAC begins in
a zero-volt-state upon power-up. A power-down mode
that reduces current consumption to 0.3µA may be initiat-
ed through a software command.
The MAX5711 is available in a small 6-pin SOT23 pack-
age. For dual and quad 10-bit versions, see the MAX5721
and MAX5741 data sheets. For single, dual, and quad
12-bit versions, see the MAX5712, MAX5722, and
MAX5742 data sheets. The MAX5711 is specified over
the automotive temperature range of -40°C to +125°C.

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.
