The MAX5144EUB+ is a +3V, serial input, voltage output, 14bit DAC in 10 pin μMAX package. It offers full 14bit performance with less than 1LSB integral linearity error and less than 1LSB differential linearity error thus ensuring monotonic performance. The unbuffered DAC output results a low supply current of 120μA and a low offset error of 2LSBs. The DAC output range is 0V to VREF. For bipolar operation, matched scaling resistors are provided in the device for use with an external precision op-amp (such as the MAX400), generating a ±VREF output swing. A 16bit 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 opto couplers for applications requiring isolation. A power-on reset circuit clears the DAC output to code 8192 when power is initially applied. A logic low on CLR asynchronously clears the DAC output to code 8192 independent of the serial interface.
