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-
tions. These devices accept a 3-wire SPI-/QSPI

MICROWIRE
®
-/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.

Static accuracy tested without load.
Linearity is tested within 20mV of GND and AVDD
,
allowing for gain and offset error.
Codes above 2047 are guaranteed to be within ±8 LSB
.
Gain and offset tested within 100mV of GND and AVDD
.
Guaranteed by design.
Device draws current in excess of the specified supply current when a digital input is driven with a voltage of VI < V
DVDD
- 0.6V
or VI > 0.5V. At VI = 2.2V with V
DVDD
= 5.25V, this current can be as high as 2mA. The SPI inputs are CMOS-input level com-
patible. The 30MHz clock frequency cannot be guaranteed for a minimum signal swing.
Note 7:
Excess current from AVDD is 10mA when powered without DVDD. Excess current from DVDD is 1mA when powered without
AVDD.
Note 8:
All timing specifications are with respect to the digital input and output thresholds.
Note 9:
Maximum daisy-chain clock frequency is limited to 25MHz.
