MAX5530/MAX5531 19-3063 Rev 0 1/04 Ultra-Low-Power, 12-Bit, Voltage-Output DACs General Description Features The MAX5530/MAX5531 are single, 12-bit, ultra-low- Ultra-Low 6A 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 6A, making them desirable for low- power and low-voltage applications. A shutdown mode Small 4mm x 4mm x 0.8mm Thin QFN Package reduces overall current, including the reference input Flexible Force-Sense-Configured Rail-to-Rail current, to just 0.18A. The MAX5530/MAX5531 use a Output Buffers 3-wire serial interface that is compatible with SPI, Internal Reference Sources 8mA of Current QSPI, and MICROWIRE. (MAX5531) At power-up, the MAX5530/MAX5531 outputs are driven Fast 16MHz 3-Wire SPI-/QSPI-/MICROWIRE- to zero scale, providing additional safety for applications Compatible Serial Interface that drive valves or for other transducers that must be off during power-up. The zero-scale outputs enable glitch- TTL- and CMOS-Compatible Digital Inputs with free power-up. Hysteresis The MAX5530 accepts an external reference input. The Glitch-Free Outputs During Power-Up MAX5531 contains an internal reference and provides an external reference output. Both devices have force- Ordering Information sense-configured output buffers. PART TEMP RANGE PIN-PACKAGE The MAX5530/MAX5531 are available in a 4mm x 4mm x 0.8mm, 12-pin, thin QFN package and are guaranteed MAX5530ETC -40C to +85C 12 Thin QFN-EP* over the extended -40C to +85C temperature range.
