The MAX5580–MAX5585 quad, 12-/10-/8-bit, voltageoutput,
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 SPI™, QSPI™, MICROWIRE™, and digital signal
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.
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 output
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.
