MAX5512MAX5515 19-3066 Rev 0 1/04 Dual, Ultra-Low-Power, 8-Bit, Voltage-Output DACs General Description Features The MAX5512MAX5515 are dual, 8-bit, ultra-low- Ultra-Low 5A Supply Current power, voltage-output, digital-to-analog converters Shutdown Mode Reduces Supply Current to (DACs) offering Rail-to-Rail buffered voltage outputs. 0.18A (max) The DACs operate from a 1.8V to 5.5V supply and con- Single +1.8V to +5.5V Supply sume less than 5A, making the devices suitable for low-power and low-voltage applications. A shutdown Small 4mm x 4mm x 0.8mm Thin QFN Package mode reduces overall current, including the reference Internal Reference Sources 8mA of Current input current, to just 0.18A. The MAX5512MAX5515 (MAX5513/MAX5515) use a 3-wire serial interface that is compatible with Flexible Force-Sense-Configured Rail-to-Rail SPI, QSPI, and MICROWIRE. Output Buffers Upon power-up, the MAX5512MAX5515 outputs are Fast 16MHz, 3-Wire, SPI-/QSPI-/MICROWIRE- driven to zero scale, providing additional safety for Compatible Serial Interface applications that drive valves or for other transducers that need to be off during power-up. The zero-scale TTL- and CMOS-Compatible Digital Inputs with outputs enable glitch-free power-up. Hysteresis The MAX5512 accepts an external reference input and Glitch-Free Outputs During Power-Up provides unity-gain outputs. The MAX5513 contains a precision internal reference and provides a buffered Ordering Information external reference output with unity-gain DAC outputs. The MAX5514 accepts an external reference input and PART TEMP RANGE PIN-PACKAGE provides force-sense outputs. The MAX5515 contains a MAX5512EUA -40C to +85C 8 MAX precision internal reference and provides a buffered MAX5513EUA -40C to +85C 8 MAX external reference output with force-sense DAC outputs. MAX5514ETC -40C to +85C 12 Thin QFN-EP* The MAX5514/MAX5515 are available in a 4mm x 4mm MAX5515ETC -40C to +85C 12 Thin QFN-EP* x 0.8mm, 12-pin, thin QFN package. The MAX5512/ MAX5513 are available in an 8-pin MAX package. All * EP = Exposed paddle (internally connected to GND). devices are guaranteed over the extended -40C to +85C temperature range.
