General Description
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 1LSB 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.

FEATUREs
♦ Full 14-Bit Performance Without Adjustments
♦ +5V Single-Supply Operation
♦ Low Power: 1.5mW
♦ 1µs Settling Time
♦ Unbuffered Voltage Output Directly Drives 60kΩ Loads
♦ SPI/QSPI/MICROWIRE-Compatible Serial Interface
♦ Power-On Reset Circuit Clears DAC Output to 0V (unipolar mode)
♦ Schmitt Trigger Inputs for Direct Optocoupler Interface
