특징 :

・ This IC has one system of digital audio interface.(I2S format, SDATA: 16 / 20 / 24bit, LRCLK: 32kHz / 44.1kHz / 48kHz, BCLK: 64fs(fixed), MCLK: 256fs / 512fs)
・ Low supply current at RESET mode.
・ The decrease in sound quality because of the change of the power supply voltage is prevented with the feedback circuitry of the output. In addition, a low noise and low distortion are achieved.
・ Eliminate large electrolytic-capacitors for high performance of Power Supply Rejection.
・ Power Limit Function. (at RL =8 , 10W /5W /OFF)
・ Available for Monaural mode.
・ Within the wide range of the power supply voltage, it is possible to operate in a single power supply. (10 to 18V)
・ It contributes to miniaturizing, making to the thin type, and the power saving of the system by high efficiency and low heat.
・ Eliminates pop noise generated when the power supply goes on/off, or when the power supply is suddenly shut off. High quality muting performance is realized by using the soft-muting technology.
・ This IC is a highly reliable design to which it has various protection functions. (High temperature protection, under voltage protection, Output short protection, Output DC voltage protection and Clock stop protection, (MCLK, BCLK, LRCLK)
・ Small package (VQFN032V5050 package) contributes to reduction of PCB area.
