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
outp ut a mp lifie r p rovid e s ra il-to-ra il outp ut s wing .
Drawing an 85µA supply current at 3V, the MAX5711 is
ideally suited to portable battery-operated equipment.
♦ Wide -40°C to +125°C Operating Temperature
Range
♦ Low 85µA Supply Current
♦ Ultra Low 0.3µA Power-Down Supply Current
♦ Single +2.7V to +5.5V Supply Voltage
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.
♦ Fast 20MHz 3-Wire SPI/QSPI/MICROWIRE and
DSP-Compatible Serial Interface
♦ Schmitt-Triggered Inputs for Direct Interfacing to
Optocouplers
♦ Rail-to-Rail Output Buffer
♦ Power-On Reset to Zero Volts
♦ Three Software-Selectable Power-Down Output
Impedances (100kΩ, 1kΩ, Hi-Z)
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-b it ve rs ions , s e e the MAX5712, MAX5722, a nd
MAX5742 data sheets. The MAX5711 is specified over
the automotive temperature range of -40°C to +125°C.
