The MAX5712 is a small footprint, low-power, 12-bit digital-
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 85µA supply current at +3V, the MAX5712 is ideally
suited for portable battery-operated equipment.
The MAX5712 utilizes a 3-wire serial-interface that is compatible
with SPI™/QSPI™/MICROWIRE™ and DSP-interface
standards. All logic inputs are CMOS-logic
compatible and buffered with Schmitt triggers to allow
direct interfacing 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 0.3µA may be
initiated through a software command.
The MAX5712 is available in a small 6-pin SOT23 package.
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.
