    • Low supply current at RESET mode.
    • Output Feedback Circuitry which prevents decrease of sound quality caused by change of power supply voltage, achieves low noise and low distortion, eliminates need for large electrolytic-capacitors
    • 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: High temperature protection, Under voltage protection, Output short protection, Output DC voltage protection, Clock stop protection (MCLK, BCLK, LRCLK)
    • Small package (VQFN024V4040)
