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.
