MAX5141MAX5144 19-1849 Rev 1 5/01 +3V/+5V, Serial-Input, Voltage-Output, 14-Bit DACs General Description Features The MAX5141MAX5144 are serial-input, voltage-output, Miniature (3mm x 5mm) 8-Pin MAX Package 14-bit digital-to-analog converters (DACs) in tiny MAX Low 120A Supply Current packages, 50% smaller than comparable DACs in an Fast 1s Settling Time 8-pin SO. They operate from low +3V (MAX5143/ MAX5144) or +5V (MAX5141/MAX5142) single supplies. 25MHz SPI/QSPI/MICROWIRE-Compatible Serial They provide 14-bit performance (1LSB INL and DNL) Interface over temperature without any adjustments. The DAC out- V Range Extends to V REF DD put is unbuffered, resulting in a low supply current of 120A and a low offset error of 2LSBs. +5V (MAX5141/MAX5142) or +3V (MAX5143/MAX5144) Single-Supply Operation The DAC output range is 0V to V For bipolar opera- REF. tion, matched scaling resistors are provided in the Full 14-Bit Performance Without Adjustments MAX5142/MAX5144 for use with an external precision op Unbuffered Voltage Output Directly Drives 60k amp (such as the MAX400), generating a V output REF Loads swing. Power-On Reset Circuit Clears DAC Output to A 16-bit serial word is used to load data into the DAC Code 0 (MAX5141/MAX5143) or Code 8192 latch. The 25MHz, 3-wire serial interface is compatible with SPI/QSPI/MICROWIRE, and can interface (MAX5142/MAX5144) directly with optocouplers for applications requiring isola- Schmitt-Trigger Inputs for Direct Optocoupler tion. A power-on reset circuit clears the DAC output to Interface code 0 (MAX5141/MAX5143) or code 8192 (MAX5142/ Asynchronous CLR MAX5144) when power is initially applied. A logic low on CLR asynchronously clears the DAC out- put to code 0 (MAX5141/MAX5143) or code 8192 (MAX5142/MAX5144), independent of the serial interface. Pin Configurations The MAX5141/MAX5143 are available in 8-pin MAX TOP VIEW packages and the MAX5142/MAX5144 are available in 10-pin MAX packages.
