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 (±1 LSB 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 2 LSBs.
The DAC output range is 0V to VREF. For bipolar operation, matched scaling resistors are provided in the MAX5142/MAX5144 for use with an external precision op amp (such as the MAX400), generating a ±VREF output swing. A 16-bit serial word is used to load data into the DAC latch. The 25MHz, 3-wire serial interface is compatible with SPI™/QSPI™/MICROWIRE™, and can interface directly with optocouplers for applications requiring isolation. A power-on reset circuit clears the DAC output to code 0 (MAX5141/MAX5143) or code 8192 (MAX5142/MAX5144) when power is initially applied. A logic low on active-low CLR asynchronously clears the DAC output to code 0 (MAX5141/MAX5143) or code 8192 (MAX5142/MAX5144), independent of the serial interface. The MAX5141/MAX5143 are available in 8-pin µMAX packages and the MAX5142/MAX5144 are available in 10-pin µMAX packages.
