MAX5580MAX5585 19-3164 Rev 4 7/08 Buffered, Fast-Settling, Quad, 12-/10-/8-Bit, Voltage-Output DACs General Description Features 3s (max) 12-Bit Settling Time to 0.5 LSB The MAX5580MAX5585 quad, 12-/10-/8-bit, voltage- output, digital-to-analog converters (DACs) offer Quad, 12-/10-/8-Bit Serial DACs in TSSOP buffered outputs and a 3s maximum settling time at the Package 12-bit level. The DACs operate from a +2.7V to +5.25V 1 LSB (max) INL and DNL at 12-Bit Resolution analog supply and a separate +1.8V to +5.25V digital Two User-Programmable Digital I/O Ports supply. The 20MHz, 3-wire, serial interface is compati- Single +2.7V to +5.25V Analog Supply ble with SPI, QSPI, MICROWIRE, and digital sig- nal processor (DSP) protocol applications. Multiple +1.8V to AV Digital Supply DD devices can share a common serial interface in direct- 20MHz, 3-Wire, SPI-/QSPI-/MICROWIRE-/DSP- access or daisy-chained configuration. The MAX5580 Compatible Serial Interface MAX5585 provide two multifunctional, user-programma- Glitch-Free Outputs Power Up to Zero Scale, ble, digital I/O ports. The externally selectable power-up Midscale, or Full Scale Controlled by PU Pin states of the DAC outputs are either zero scale, mid- Unity-Gain or Force-Sense-Configured scale, or full scale. Software-selectable FAST and SLOW Output Buffers settling modes decrease settling time in FAST mode, or reduce supply current in SLOW mode. Applications The MAX5580/MAX5581 are 12-bit DACs, the Portable Instrumentation MAX5582/MAX5583 are 10-bit DACs, and the Automatic Test Equipment (ATE) MAX5584/MAX5585 are 8-bit DACs. The MAX5580/ Digital Offset and Gain Adjustment MAX5582/MAX5584 provide unity-gain-configured out- Automatic Tuning put buffers, while the MAX5581/MAX5583/MAX5585 Programmable Voltage and Current Sources provide force-sense-configured output buffers. The MAX5580MAX5585 operate over the extended -40C Programmable Attenuators to +85C temperature range and are available in a Industrial Process Controls space-saving, 6.5mm x 4.4mm, 20-pin, TSSOP package.
