General Description

The MAX5590–MAX5595 octal, 12/10/8-bit, voltage-out-

put 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 direct-access or

daisy-chained configuration. The MAX5590–MAX5595

provide two multifunction, 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 MAX5590/MAX5591 are 12-bit DACs, the MAX5592/

MAX5593 are 10-bit DACs, and the MAX5594/

MAX5595 are 8-bit DACs. The MAX5590/MAX5592/

MAX5594 provide unity-gain-configured output buffers,

while the MAX5591/MAX5593/MAX5595 provide force-

sense-configured output buffers. The MAX5590–

MAX5595 are specified over the extended -40°C to

+85°C temperature range, and are available in space-

saving 24-pin and 28-pin TSSOP packages.
