General Description

The MAX5512–MAX5515 are dual, 8-bit, ultra-low-

power, voltage-output, digital-to-analog converters

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.
