General Description
The MAX5141–MAX5144 are serial-input, voltage-output, 14-bit digital-to-analog converters (DACs) in tiny µMAX packages, 50% smaller than comparable DACs in an 8-pin SO. They operate from low +3V (MAX5143/MAX5144) or +5V (MAX5141/MAX5142) single supplies. They provide 14-bit performance (±1LSB INL and DNL) over temperature without any adjustments. The DAC output is unbuffered, resulting in a low supply current of 120µA and a low offset error of 2LSBs.
