General Description

The MAX5441–MAX5444 are serial-input, voltage-output, 16-bit digital-to-analog converters (DACs) in tiny μMAX? packages, 50 smaller than comparable DACs in 8-pin SOs. They operate from low +3V (MAX5443/MAX5444) or +5V (MAX5441/MAX5442) single supplies. They provide 16-bit performance (±2LSB INL and ±1LSB DNL) over temperature without any adjustments. Unbuffered DAC outputs result in a low supply current of 120μA and a low offset error of 2LSB.
