MAX5441AEUA+

The MAX5441AEUA+ is a serial input, voltage output, 16bit digital to analogue converter (DAC) in 8 pin µMAX package. This device operates from low +5V single supply and 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 optocouplers for applications requiring isolation. A power-on reset circuit clears the DAC output to code 0 when power is initially applied and logic low on complementary CLR asynchronously clears the DAC output to code 0 independent of the serial interface. The MAX5441A is used in high resolution offset and gain adjustment, automated test equipment and data acquisition systems.
