The MAX5522-MAX5525 are dual, 10-bit, ultra-lowpower,
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 lowpower
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.
