Dual, Ultra-Low-Power,
8-Bit, Voltage-Output DACs
General Description
The MAX5512–MAX5515 are dual, 8-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 con-
sume 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 MAX5512–MAX5515
use a 3-wire serial interface that is compatible with
SPI™, QSPI™, and MICROWIRE™.
Upon power-up, the MAX5512–MAX5515 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 MAX5512 accepts an external reference input and
provides unity-gain outputs. The MAX5513 contains a
precision internal reference and provides a buffered
external reference output with unity-gain DAC outputs.
The MAX5514 accepts an external reference input and
provides force-sense outputs. The MAX5515 contains a
precision internal reference and provides a buffered
external reference output with force-sense DAC outputs.
The MAX5514/MAX5515 are available in a 4mm x 4mm
x 0.8mm, 12-pin, thin QFN package. The MAX5512/
MAX5513 are available in an 8-pin µMAX package. All
devices are guaranteed over the extended -40°C to
+85°C temperature range.
For 10-bit compatible devices, refer to the MAX5522–
MAX5525 data sheet. For 12-bit compatible devices,
refer to the MAX5532–MAX5535 data sheet.

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.
