GENERAL DESCRIPTION

The TDA1314T is a quadruple very low noise high dynamic range DAC which is intended for use in motor cars and is controlled by the car radio DSP. Each channel incorporates an 8th-order IIR up-sampling filter from 1ASF to 4ASF followed by a 1st-order noise shaper and DAC. The DAC currents are converted to audio voltage signals using operational amplifiers (one per channel).

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.
