Pin-/Software-Compatible,
16-/12-Bit, Voltage-Output DACs
4–MAX5137
General Description
Features
♦ 16-/12-Bit Resolution Available in a 4mm x 4mm,
The MAX5134–MAX5137 is a family of pin-compatible
and software-compatible 16-bit and 12-bit DACs. The
MAX5134/MAX5135 are low-power, quad 16-/12-bit,
buffered voltage-output, high-linearity DACs. The
MAX5136/MAX5137 are low-power, dual 16-/12-bit,
buffered voltage-output, high-linearity DACs. They use
a precision internal reference or a precision external ref-
erence for rail-to-rail operation. The MAX5134–MAX5137
accept a wide +2.7V to +5.25V supply-voltage range to
accommodate most low-power and low-voltage applica-

♦ Hardware-Selectable to Zero/Midscale DAC
Output on Power-Up or Reset
♦ Double-Buffered Input Registers
♦ LDAC Asynchronously Updates DAC Outputs
Simultaneously
♦ READY Facilitates Daisy Chaining
♦ High-Performance 10ppm/°C Internal Reference
♦ Guaranteed Monotonic Over All Operating
tions. These devices accept a 3-wire SPITM-/QSPITM
-
/MICROWIRETM-/DSP-compatible serial interface to save
board space and reduce the complexity of optically iso-
lated and transformer-isolated applications. The digital
interface’s double-buffered hardware and software
LDAC provide simultaneous output updates. The serial
interface features a READY output for easy daisy-chain-
ing of several MAX5134–MAX5137 devices and/or other
compatible devices. The MAX5134–MAX5137 include a
hardware input to reset the DAC outputs to zero or mid-
scale upon power-up or reset, providing additional safety
for applications that drive valves or other transducers
that need to be off during power-up. The high linearity of
the DACs makes these devices ideal for precision con-
trol and instrumentation applications. The MAX5134–
MAX5137 are available in an ultra-small (4mm x 4mm),
24-pin TQFN package or a 16-pin TSSOP package. Both
packages are specified over the -40°C to +105°C
extended industrial temperature range.
