General Description
The MAX5712 is a small footprint, low-power, 12-bit digi-
tal-to-analog converter (DAC) that operates from a single
+2.7V to +5.5V supply. The MAX5712 on-chip precision
output amplifier provides rail-to-rail output swing. Drawing
only 85A supply current at +3V, the MAX5712 is ideally
suited for portable battery-operated equipment.
The MAX5712 utilizes a 3-wire serial-interface that is com-
patible 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 MAX5712 incorporates a power-
on reset (POR) circuit that ensures the DAC begins in a
zero-volt-state upon power-up. A power-down mode that
reduces current consumption to 0.3A may be initiated
through a software command.
The MAX5712 is available in a small 6-pin SOT23 pack-
age. For dual and quad 12-bit versions, see the MAX5722
and MAX5742 data sheets. For single, dual, and quad
10-bit versions, see the MAX5711, MAX5721 and
MAX5741 data sheets. The MAX5712 is specified over
the automotive temperature range of -40°C to +125°C.
