The MAX5532–MAX5535 are dual, 12-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 MAX5532–MAX5535 use a
3-wire serial interface that is compatible with SPI™,
QSPI™, and MICROWIRE™.
Upon power-up, the MAX5532–MAX5535 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 MAX5532 accepts an external reference input and
provides unity-gain outputs. The MAX5533 contains a
precision internal reference and provides a buffered
external reference output with unity-gain DAC outputs.
The MAX5534 accepts an external reference input and
provides force-sense outputs. The MAX5535 contains a
precision internal reference and provides a buffered
external reference output with force-sense DAC outputs.
The MAX5534/MAX5535 are available in a 4mm x 4mm
x 0.8mm, 12-pin, thin QFN package. The MAX5532/MAX5533 are available in an 8-pin µMAX® package. All
devices are guaranteed over the extended -40°C to
+85°C temperature range.

MAX5522–MAX5525 data sheet. For 8-bit compatible devices, refer to the
MAX5512–MAX5515 data sheet.
