The CS83601E is a Class R audio power amplifier with built-in BOOST module with anti-crack function. It can provide up to 11W constant power for a 2Ω load. Class AB and Class D switchable mode design, to minimize the audio subsystem power amplifier interference to FM, CS83601E in the lithium battery supply voltage range to provide the ultimate power output, making CS83601E portable speaker equipment, especially amplifier products the best choice.
    The CS83601E's fully differential architecture and extremely high PSRR effectively improve the CS83601E's ability to suppress RF noise. The filter-free PWM modulation structure and built-in BOOST boost module, as well as the CS83601E's proprietary AERC (Adaptive Edge Rate Control) technology, greatly reduces EMI interference in the full bandwidth range of audio. The 60cm audio line has a margin of more than 20dB under the FCC standard, and the CS83601E has built-in overcurrent protection, short circuit protection and overheat protection, which effectively protects the chip from being damaged under abnormal working conditions.
    The CS83601E is available in a small ESOP10L package with a rated operating temperature range of -40 ° C to 85 ° C.
