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.
