NXP Semiconductors TDA1314T
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).| Part No. | TDA1314T |

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 specified.
