General Description
The MAX5580–MAX5585 quad, 12-/10-/8-bit, voltage-
output, 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 compati-
ble with SPI™, QSPI™, MICROWIRE™, and digital sig-
nal processor (DSP) protocol applications. Multiple
devices can share a common serial interface in direct-
access or daisy-chained configuration. The MAX5580–
MAX5585 provide two multifunctional, user-programma-
ble, digital I/O ports. The externally selectable power-up
states of the DAC outputs are either zero scale, mid-
scale, or full scale. Software-selectable FAST and SLOW
settling modes decrease settling time in FAST mode, or
reduce supply current in SLOW mode.
The MAX5580/MAX5581 are 12-bit DACs, the
MAX5582/MAX5583 are 10-bit DACs, and the
MAX5584/MAX5585 are 8-bit DACs. The MAX5580/
MAX5582/MAX5584 provide unity-gain-configured out-
put buffers, while the MAX5581/MAX5583/MAX5585
provide force-sense-configured output buffers. The
MAX5580–MAX5585 operate over the extended -40°C
to +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.
