NXP Semiconductors TDA1307
The TDA1307 is an advanced oversampling digital filter employing bitstream conversion technology, which has been designed for use in premium performance digital audio applications. 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, TDA1307 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.
