MAX5713/MAX5714/MAX5715
Ultra-Small, Quad-Channel, 8-/10-/12-Bit Buffered
Output DACs with Internal Reference and SPI Interface
General Description
Benefits and Features
The MAX5713/MAX5714/MAX5715 4-channel, low-power,
8-/10-/12-bit, voltage-output digital-to-analog converters
(DACs) include output buffers and an internal reference
that is selectable to be 2.048V, 2.500V, or 4.096V. The
MAX5713/MAX5714/MAX5715 accept a wide supply
voltage range of 2.7V to 5.5V with extremely low power
(3mW) consumption to accommodate most low-voltage
applications. A precision external reference input allows
rail-to-rail operation and presents a 100kI (typ) load to
an external reference.
The MAX5713/MAX5714/MAX5715 have a 50MHz 3-wire
SPI/QSPI™/MICROWIRE®/DSP-compatible serial interface
that also includes a RDY output for daisy-chain applica-
tions. The DAC output is buffered and has a low supply
current of less than 250FA per channel and a low off-
set error of Q0.5mV (typ). On power-up, the MAX5713/
MAX5714/MAX5715 reset the DAC outputs to zero, pro-
viding additional safety for applications that drive valves
or other transducers which need to be off on power-up.
The internal reference is initially powered down to allow
use of an external reference. The MAX5713/MAX5714/
MAX5715 allow simultaneous output updates using soft-
ware LOAD commands or the hardware load DAC logic
input (LDAC).
A clear logic input (CLR) allows the contents of the CODE
and the DAC registers to be cleared asynchronously and
sets the DAC outputs to zero. The MAX5713/MAX5714/
MAX5715 are available in a 14-pin TSSOP and an ultra-
small, 12-bump WLP package and are specified over the
-40NC to +125NC temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
