General Description

The MAX5541 serial-input, voltage-output, 16-bit monotonic digital-to-analog converter (DAC) operates from a single +5V supply. The DAC output is unbuffered, resulting in a 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 (POR) circuit clears the DAC output to 0V (unipolar mode) when power is initially applied.
