Quadruple lter DAC
FEATURES High dynamic range to enable digital DSP (Digital Signal Processor) volume control 18 bits data input format for each of the four channels Four times bit-serial oversampling filter 1st-order 4fas (audio sampling frequency) noise shaper Four very low noise DACs Only 1st-order analog post filtering required Smooth power-on of the DAC output currents Because of the automatic digital PLL divider range setting the master clock is selectable in a wide 4fas integer range Insensitive to jitter on the I2S-bus signals with respect to the DAC total harmonic distortion deterioration. QUICK REFERENCE DATA Vref = 2.5 and 5 V; Tamb = 25 °C; all voltages referenced to ground; unless otherwise specied.
