MAX5711

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.
