Description
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 supply.
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 provide
unity-gain-configured output buffers, while the MAX5291/MAX5293/MAX5295 provide force-sense-configured 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.
