TDA1314T Overview
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).
TDA1314T Key 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
