The CS8330C is a Class R mono audio power amplifier that can be used for dual power supply applications with a single lithium battery and a 12V adapter, suitable for each power supply node from 2.7 to 12V, external gain adjustment, with four anti-break modes,AB/D switching, power limitation, built-in BOOST booster module and adaptive boost booster module.
    In the case of a single lithium battery, the CS8330C can drive loads as low as 4Ω, with a maximum output of 15W constant power; The CS8330C can drive loads as low as 3Ω with a maximum output of 18W of constant power when powered by two lithium batteries in series. In the case of 12V adapter power supply, CS8330C BOOST module is turned off, and its power amplifier module can drive 4 ohm load output 20W power; CS8330C Class AB Class D switchable mode design, minimize the audio subsystem power amplifier interference to FM, for the end product to provide a more extreme power output.
    The CS8330C's fully differential architecture and extremely high PSRR effectively improve the ability to suppress RF noise. No filter PWM modulation structure and built-in BOOST boost module, and CS8330C adopts proprietary AERC(Adaptive Edge Rate Control) technology, greatly reducing EMI interference in the full bandwidth range of audio, 60cm audio line, In the FCC standard with more than 20dB margin, in addition CS8330C built-in overcurrent protection, short circuit protection and overheating protection, effective protection chip under abnormal working conditions will not be damaged.

    The CS8330C offers a small TSSOP20-PP package with a rated operating temperature range of -40 ° C to 85 ° C.

Available in TSSOP20-PP package
