MAX5443：+3V/+5V、串行输入、电压输出、16位DAC

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 (±2 LSB INL and ±1 LSB DNL) over temperature without any adjustments. Unbuffered DAC outputs result in a low supply current of 120µA and a low offset error of 2 LSB. The DAC output ranges from 0 to VREF. For bipolar operation, matched scaling resistors are provided in the MAX5442/MAX5444 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 (MAX5441/MAX5443) or code 32768 (MAX5442 /MAX5444) when power is initially applied. A logic low on active-low CLR asynchronously clears the DAC output to code 0 (MAX5441/MAX5443) or code 32768 (MAX5442/MAX5444) independent of the serial interface. The MAX5441/MAX5443 are available in 8-pin µMAX packages. The MAX5442/MAX5444 are available in 10-pin µMAX packages.
