8.3.7 DAC Signal-Chain

Figure 8-17 shows the key components of the playback signal chain.
GUID-20231202-SS0I-0CTR-4SQC-WNDVNHPKS500-low.svg Figure 8-17 DAC Signal-Chain Processing Flowchart

The DAC signal chain offers a highly flexible low-noise playback path for low-noise and high-fidelity audio applications. This low-noise and low-distortion, multibit, delta-sigma DAC enables the TAC5242 to achieve 120 dB dynamic range in very low power. Moreover, the DAC architecture has inherent antialias filtering with a high rejection of out-of-band frequency noise around multiple modulator frequency components. Therefore, the device prevents noise from aliasing into the audio band. The TAC5242 also integrates, high-performance multistage digital interpolation filter sharply cuts off any out-of-band frequency noise with high stop-band attenuation.
