特性 Features

? This IC includes the DSP (digital sound processor) for Audio signal processing for Flat TVs.
? This IC has two input systems of digital audio interface. (I2S/LJ/RJ format, LRCLK: 32 kHz/ 44.1kHz / 48kHz, SYS_CLK: 256fs / 512fs, BCLK: 48fs / 64fs, SDATA: 16 / 20 / 24bit)
? With wide range of power supply voltage, it is possible to operate with single power supply. (Vcc = 10~26V)
? With high efficiency and low heat dissipation contributing to miniaturization, slim design, and also power saving of the system.
? S/N of the system can be optimized by adjusting the gain selection in 16 steps. (20~35dB,1dB/step)
? With built-in feedback circuitry at the output, prevents the decrease in sound quality due to change in power supply voltage. In addition, low noise and low distortion are achieved.
? With a built-in DAC provides best stereo-output for headphone function. As a result, the selection of output of the digital input in two systems is possible.
8) It has additional S/PDIF output for the LINE output usage.
9) Eliminates pop-noise generated during the power supply on/off. High quality muting performance is realized by using the soft-muting technology.
10) This IC is built-in with various protection functions for highly reliability design. (High temperature protection, Under voltage protection, Output short protection, Output DC-Voltage protection and Clock stop protection).
