  • ・ This IC includes the DSP (digital sound processor) for Audio signal processing for Flat TVs. P2Bass+( pseudo bass), 16 Band P-EQ, Level DRC, 2 Band DRC, Surround, etc.
    ・ This IC has one input systems of digital audio interface. (No needs of Master Clock) - I2S / LJ / RJ format - LRCLK: 32k/44.1k/48KHz - BCLK: 32fs / 48fs / 64fs - SDATA: 16 / 20 / 24bit
    ・ With wide range of power supply voltage.
    ・ The monaural output that can reduce the number of external parts can be used.
    ・ With high efficiency and low heat dissipation contributing to miniaturization, slim design, and also power saving of the system.
    ・ Eliminates pop-noise generated during the power supply on/off. High quality muting performance is realized by using the soft-muting technology.
    ・ This IC is built-in with various protection functions for highly reliability design. - High temperature protection - Over voltage protection, Under voltage protection - Output short protection - DC voltage protection - Clock stop protection
    ・ Small package
    ・ The Audio output amplifier of the unnecessary output coupling capacitor. - Adjust gain (Via external parts) - 2Vrms output (SVDD=3.3V, RL =10kΩ) or 35mW output (SVDD=3.3V, RL =32Ω)
