Dual, Ultra-Low-Power, 10-Bit, Voltage-Output DACs
General DescriptionThe MAX5522–MAX5525 are dual, 10-bit, ultra-low-
power, voltage-output, digital-to-analog converters
(DACs) offering rail-to-rail buffered voltage outputs. The
DACs operate from a 1.8V to 5.5V supply and consume
less than 5µA, making the devices suitable for low-
power and low-voltage applications. A shutdown mode
reduces overall current, including the reference input
current, to just 0.18µA. The MAX5522–MAX5525 use a
3-wire serial interface that is compatible with SPI™,
QSPI™, and MICROWIRE™.
Upon power-up, the MAX5522–MAX5525 outputs are
driven to zero scale, providing additional safety for
applications that drive valves or for other transducers
that need to be off during power-up. The zero-scale
outputs enable glitch-free power-up.
The MAX5522 accepts an external reference input and
provides unity-gain outputs. The MAX5523 contains a
precision internal reference and provides a buffered
external reference output with unity-gain DAC outputs.
The MAX5524 accepts an external reference input and
provides force-sense outputs. The MAX5525 contains a
precision internal reference and provides a buffered
external reference output with force-sense DAC outputs.
The MAX5524/MAX5525 are available in a 4mm x 4mm
x 0.8mm, 12-pin, thin QFN package. The MAX5522/
MAX5523 are available in an 8-pin µMAX package. All
devices are guaranteed over the extended -40°C to
+85°C temperature range.
For 12-bit compatible devices, refer to the MAX5532–
MAX5535 data sheet. For 8-bit compatible devices,
refer to the MAX5512–MAX5515 data sheet.

ELECTRICAL CHARACTERISTICS(VDD = +1.8Vto +5.5V, OUT_ unloaded, TA= TMINto TMAX, unless otherwise noted. Typical values are at TA= +25°C.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation 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.
