MAX5711 Datasheet, PDF (1/9 Pages) Maxim Integrated Products – 10-Bit, Low-Power, Rail-to-Rail Voltage-Output Serial DAC in SOT23

19-2195; Rev 0; 10/01
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.
