특징 :

・ With wide range of power supply voltage. (VCC=10 to 26V)
・ This IC includes the DSP (digital sound processor) for Audio signal processing for Flat TVs. Synchronous SRC, Surround, 8 Band EQ, 1 Band EQ (for Sub), Volume, 2 Band DRC, Delay RAM for phase revised Close Over Filter, 512 Taps FIR Filter, P2Volume, P2Base+, Higher Sound Complement (High Generator), Soft Clipper, Hard Clipper
・ This IC has two inputs systems of digital audio interface. I2S / LJ / RJ format, LRCLK: 8 to 192 kHz, BCLK: 32fs / 48fs / 64fs, SDATA: 16 / 20 / 24bits BCLK: 32fs / 48fs / 64fs, SDATA: 16 / 20 / 24bits
・ Two Digital Audio Output for Audio DAC and headphone.
・ One PWM Output for Subwoofer.
・ The sound quality decrease by the power supply variation is prevented with the output feedback circuit. In addition, a low noise and a low distortion are achieved. Mass electrolytic capacitor is unnecessary because it is strong in the power supply variation.
・ It contributes to miniaturizing, making to the thin type, and the power saving of the system by highly effective (10W+10W output and 8 on-load) 90% and low generation of heat.
・ Low current at the Power down Mode.
・ The pop noise at power supply on/off is prevented, and a more high-quality soft mute function is built into. Highly reliable design with built-in various protection functions.
・ The component side product can be decreased because of small package (UQFN056V7070).
・ The maximum output in the stereo is 25W+25W (VCC=20.5V, 8 load).
・ The maximum output in the monaural(PBTL) is 50W(VCC=20.5V, 4 load)
