MAX5444AEUB+

The MAX5444AEUB+ is a serial input, voltage output, 16bit digital to analogue converter (DAC) in 10 pin µMAX package. It provides 16bit performance (±2LSB INL and ±1LSB DNL) over temperature without any adjustments. Unbuffered DAC output result in a low supply current of 120µA and low offset error of 2LSB. The DAC output ranges from 0 to VREF and a 16bit serial word is used to load data into DAC latch. The 25MHz, 3-wire serial interface is compatible with SPI/QSPI/MICROWIRE and can interface directly with opto couplers for applications requiring isolation. A power-on reset circuit clears the DAC output to code 32768 when power is initially applied and logic low on CLR (active-low) asynchronously clears the DAC output to code 32768 independent of the serial interface. It is used in high-resolution offset and gain adjustment, industrial process control, automated test equipment and data-acquisition systems.
