MAX5533

    The MAX5532(R)/MAX5533/CMAX5535 are dual, 12-bit, ultra-low power, voltage-output, digital-to-analog converter (DACs) offering Rail-to-Rail^® buffered voltage outputs.The DACs operate from a 1.8V to 5.5V supply and consume less than 5A, making the devices suitable for low-power and low-voltage applications. A shutdown mode reduces overall current, including the reference input current, to just 0.18A. The MAX5532-CMAX55(MAX5533) use a 3-wire serial interface that is compatible with SPI™, QSPI™, and MICROWIRE™.

    Upon power-up, the MAX5532-CMAX5535(MAX5533) 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 PAMAX package. All devices are guaranteed over the extended -40 to +85 temperature range.
