特性 Features

? 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(fixed))
? 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.
? S/N of the system can be optimized by adjusting the gain setting among 2 steps. (20dB / 26dB)
? Available for Monaural mode.
? Within the wide range of the power supply voltage, it is possible to operate in a single power supply. (10～18V)
? It contributes to miniaturizing, making to the thin type, and the power saving of the system by high efficiency and low heat.
8) 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.
9) 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))
10) Small package (HTSSOP-B28 package) contributes to reduction of PCB area.
