The MAX5290–MAX5295 dual, 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 3.6V digital sup-

ply. The 20MHz 3-wire serial interface is compatible

with SPI™, QSPI™, MICROWIRE™, and digital signal

processor (DSP) protocol applications. Multiple devices

can share a common serial interface in direct access or

daisy-chained configuration. The MAX5290–MAX5295

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.

The MAX5290/MAX5291 are 12-bit DACs, the MAX5292/

MAX5293 are 10-bit DACs, and the MAX5294/MAX5295

are 8-bit DACs. The MAX5290/ MAX5292/MAX5294 pro-

vide unity-gain-configured output buffers, while the

MAX5291/MAX5293/MAX5295 provide force-sense-con-

figured output buffers. The MAX5290– MAX5295 are

specified over the extended -40°C to +85°C temperature

range, and are available in space-saving 4mm x 4mm,

16-pin thin QFN and 6.5mm x 5mm, 14-pin and 16-pin

TSSOP packages.
