MAX5544:Low-Cost, +5V, Serial-Input, Voltage-Output, 14-Bit DAC

Lowest Cost 14-Bit DAC

The MAX5544 serial-input, voltage-output, 14-bit monotonic digital-to-analog converter (DAC) operates from a single +5V supply. The DAC output is unbuffered, resulting in low 0.3mA supply current and low 1 LSB offset error. The DAC output range is 0V to VREF. The DAC latch accepts a 16-bit serial word. A power-on reset circuit clears the DAC output to 0V (unipolar mode) when power is initially applied. The 10MHz 3-wire serial interface is SPI™/QSPI™/MICROWIRE™ compatible and interfaces directly with optocouplers for applications requiring isolation. The MAX5544 is available in an 8-pin SO package.
