MAX5290MAX5295 19-3005 Rev 3 7/07 Buffered, Fast-Settling, Dual, 12-/10-/8-Bit, Voltage-Output DACs General Description Features The MAX5290MAX5295 dual, 12-/10-/8-bit, voltage- Dual, 12-/10-/8-Bit Serial DACs in 4mm x 4mm output digital-to-analog converters (DACs) offer Thin QFN and TSSOP Packages buffered outputs and a 3s maximum settling time at 3s (max) 12-Bit Settling Time to 1/2 LSB the 12-bit level. The DACs operate from a 2.7V to 5.25V analog supply and a separate 1.8V to 3.6V digital sup- Integral Nonlinearity ply. The 20MHz 3-wire serial interface is compatible 1 LSB (max) MAX5290/MAX5291 A-Grade (12-Bit) with SPI, QSPI, MICROWIRE, and digital signal 1 LSB (max) MAX5292/MAX5293 (10-Bit) processor (DSP) protocol applications. Multiple devices 1/2 LSB (max) MAX5294/MAX5295 (8-Bit) can share a common serial interface in direct access or daisy-chained configuration. The MAX5290MAX5295 Guaranteed Monotonic, 1 LSB (max) DNL provide two multifunctional, user-programmable, digital Two User-Programmable Digital I/O Ports I/O ports. The externally selectable power-up states of the DAC outputs are either zero scale, midscale, or full Single +2.7V to +5.25V Analog Supply scale. Software-selectable FAST and SLOW settling +1.8V to AV Digital Supply DD modes decrease settling time in FAST mode, or reduce supply current in SLOW mode. 20MHz 3-Wire SPI-/QSPI-/MICROWIRE- and The MAX5290/MAX5291 are 12-bit DACs, the MAX5292/ DSP-Compatible Serial Interface MAX5293 are 10-bit DACs, and the MAX5294/MAX5295 Glitch-Free Outputs Power Up to Zero Scale, are 8-bit DACs.
