+3V/+5V, Serial-Input, Voltage-Output, 16-Bit DACs

Product Details

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.

Description

The MAX544X evaluation kit (EV kit) provides a proven design to evaluate the MAX5441–MAX5442 serial-input, voltage-output, 16-bit digital-to-analog convertors (DACs). The EV kit also includes Windows XP®-, Windows Vista®-, and Windows® 7-compatible software that provides a simple graphical user interface (GUI) for exercising the features of these devices.
The DACs are controlled by an on-board MAXQ® microcontroller, which provides two separate SPI control interfaces.
The EV kit provides on-board +2.5V and +4.096V highprecision voltage references (MAX6126). The EV kit also provides precision bipolar and ultra-precision unipolar op amps, the MAX9632 (single) and MAX44251 (dual), respectively.
The EV kit comes with the +5V MAX5441AEUA+ and +5V MAX5442AEUB+ installed; however, it can also be used to evaluate other parts in the same family. Contact the factory for free samples of the pin-compatible devices shown in Table 1 in the full data sheet.
