General Description
The MAX5580MAX5585 quad, 12-/10-/8-bit, voltageo u t p u t , digital-to-analog converters (DACs) offer buffered outputs and a 3µs maximum settling time at the 12-bit level. The DACs operate from a +2.7V to +5.25V analog supply and a separate +1.8V to +5.25V digital supply. The 20MHz, 3-wire, serial interface is compatible with SPITM, QSPITM, MICROWIRETM, and digital sign a l processor (DSP) protocol applications. Multiple devices can share a common serial interface in directaccess or daisy-chained configuration. The MAX5580 MAX5585 provide two multifunctional, user-programmable, digital I/O ports. The externally selectable power-up states of the DAC outputs are either zero scale, midscale, or full scale. Software-selectable FAST and SLOW settling modes decrease settling time in FAST mode, or reduce supply current in SLOW mode. T h e MAX5580/MAX5581 are 12-bit DACs, the M A X 5 5 8 2 / M A X 5 5 8 3 are 10-bit DACs, and the M A X 5 5 8 4 / M A X 5 5 8 5 are 8-bit DACs. The MAX5580/ MAX5582/MAX5584 provide unity-gain-configured output buffers, while the MAX5581/MAX5583/MAX5585 p r o v i d e force-sense-configured output buffers. The MAX5580MAX5585 operate over the extended -40°C t o +85°C temperature range and are available in space-saving, 5mm x 5mm x 0.8mm, 20-pin, thin QFN and TSSOP packages.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
