I²S format
SDATA: 16 / 20 / 24bit
LRCLK (fS): 32kHz / 44.1kHz / 48kHz
BCLK: 64fS (fixed)
MCLK: 256fS / 512fS Automatic Identification - Low supply current at RESET mode.
- Slew rate controller
; No need snubber circuit (VCC ≤ 22V) - Output Feedback Circuitry which prevents decrease
of sound quality caused by change of power supply
voltage, achieves low noise and low distortion,
So the large electrolytic-capacitors for VCC
bypass is able to be eliminated. - Variable Gain (17dB / 20dB / 26dB)
- Wide power supply voltage range (8.5V to 24V)
- High efficiency, low heat
- Pop noise prevention at power supply on / off
- Soft Muting Technology
- High reliability design by built-in protection circuits
- Overheat protection
- Under voltage protection
- Output short protection
- Output DC voltage protection
- Clock stop protection (MCLK, BCLK, LRCLK)
- Small package (VQFN024V4040)
