The MAX5590–MAX5595 octal, 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 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.
