Description

The TDA1307 is an advanced oversampling digital filter employing bitstream conversion technology, which has been designed for use in premium performance digital audio applications. Audio data is input to the TDA1307 through its multiple-format interface. Any of the four formats (I2S, Sony 16, 18 or 20-bit) are acceptable. By using a highly accurate audio data processing structure, including 8 times oversampling digital filtering and up to 4th order noise shaping, a high quality bitstream is produced which, when used in the recommended combination with the TDA1547 bitstream DAC, provides the optimum in dynamic range and signal-to-noise performance. With the TDA1307, a high degree of versatility is achieved by a multitude of functional features and their easy accessibility; error concealment functions,audio peak data information and an advanced patented digital fade function are accessible through a simple microprocessor command interface, which also provides access to various integrated system settings and functions.

TDA1307 plus TDA1547 high-performance bitstream digital filter plus DAC combination:
