Buffered, Fast-Settling, Quad,

12-/10-/8-Bit, Voltage-Output DACs

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 a

space-saving, 6.5mm x 4.4mm, 20-pin, TSSOP package.
