MAX5441MAX5444 19-1846 Rev 3 1/09 +3V/+5V, Serial-Input, Voltage-Output, 16-Bit DACs General Description Features The MAX5441MAX5444 are serial-input, voltage-out- Ultra-Small 3mm x 5mm 8-Pin MAX Package put, 16-bit digital-to-analog converters (DACs) in tiny Low 120A Supply Current MAX packages, 50% smaller than comparable DACs Fast 1s Settling Time in 8-pin SOs. They operate from low +3V (MAX5443/ MAX5444) or +5V (MAX5441/MAX5442) single sup- 25MHz SPI/QSPI/MICROWIRE-Compatible Serial plies. They provide 16-bit performance (2LSB INL and Interface 1LSB DNL) over temperature without any adjustments. V Range Extends to V REF DD Unbuffered DAC outputs result in a low supply current +5V (MAX5441/MAX5442) or +3V of 120A and a low offset error of 2LSB. (MAX5443/MAX5444) Single-Supply Operation The DAC output ranges from 0 to V . For bipolar REF Full 16-Bit Performance Without Adjustments operation, matched scaling resistors are provided in the MAX5442/MAX5444 for use with an external preci- Unbuffered Voltage Output Directly Drives sion op amp (such as the MAX400), generating a 60k Loads V output swing. REF Power-On Reset Circuit Clears DAC Output to Code 0 (MAX5441/MAX5443) or Code 32768 A 16-bit serial word is used to load data into the DAC (MAX5442/MAX5444) latch. The 25MHz, 3-wire serial interface is compatible with SPI/QSPI/MICROWIRE, and can interface directly Schmitt-Trigger Inputs for Direct Optocoupler with optocouplers for applications requiring isolation. A Interface power-on reset circuit clears the DAC output to code 0 Asynchronous CLR (MAX5441/MAX5443) or code 32768 (MAX5442 /MAX5444) when power is initially applied.
