Numéro de sérieMAX5580
CategorieData Conversion => DAC (Digital to Analog Converters) => 10-14 bit => 12 bit
DescriptionBuffered, Fast-Settling, Quad, 12-/10-/8-Bit, Voltage-Output DACs
The MAX5580–MAX5585 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 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 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.

    3µs (max) 12-Bit Settling Time to 0.5 LSB Quad, 12-/10-/8-Bit Serial DACs in TSSOP Package ±1 LSB (max) INL and DNL at 12-Bit Resolution Two User-Programmable Digital I/O Ports Single to +5.25V Analog Supply +1.8V to AVDD Digital Supply 20MHz, 3-Wire, SPI-/QSPI-/MICROWIRE-/DSPCompatible Serial Interface Glitch-Free Outputs Power Up to Zero Scale, Midscale, or Full Scale Controlled by PU Pin Unity-Gain or Force-Sense-Configured Output Buffers

    The MAX5580­MAX5585 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 to +5.25V analog supply and a separate to +5.25V digital supply. The 20MHz, 3-wire, serial interface is compatible with SPITM, QSPITM, MICROWIRETM, 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 MAX5580­MAX5585 operate over the extended to +85°C temperature range and are available in a space-saving, 4.4mm, 20-pin, TSSOP package.

    Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
