PRODUCTION DATA
The mono audio DAC consists of a digital audio processing block, a digital interpolation filter, a digital delta-sigma modulator, and an analog reconstruction filter. The high oversampling ratio (normally DOSR is between 32 and 128) exhibits good dynamic range by ensuring that the quantization noise generated within the delta-sigma modulator stays outside of the audio frequency band. Audio analog outputs include mono class-D speaker outputs. Because the TAS2505-Q1 contains a mono DAC, it inputs the mono data from the left channel, the right channel, or a mix of the left and right channels as [(L + R) ÷ 2], selected by page 0, register 63, bits D5–D4.
For more detailed information see the TAS2505 Application Reference Guide (SLAU472).
