MAX5580

The MAX5580MAX5585 quad, 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 compati-ble with SPI™, QSPI™, MICROWIRE™, and digital sig-nal processor (DSP) protocol applications. Multiple devices can share a common serial interface in direct-access or daisy-chained configuration. The MAX5580MAX5585 provide two multifunctional, user-programma-ble, digital I/O ports. The externally selectable power-up states of the DAC outputs are either zero scale, mid-scale, 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 out-put buffers, while the MAX5581/MAX5583/MAX5585 provide force-sense-configured output buffers. The MAX5580MAX5585 operate over the extended -40°C to +85°C temperature range and are available in space-saving, 5mm x 5mm x 0.8mm, 20-pin, thin QFN and TSSOP packages.
