IU8373 is compatible with CS83711, powered by two lithium batteries with 8.4V, built-in boost 17W stereo Class D audio amplifier IC

IU8373 takes into account the 12V adapter power supply application, two anti-breaking sound modes, spread spectrum mode, built-in BOOST boost module, dual lithium battery series power supply, constant 2×17W output power R class stereo audio power amplifier, the pin is fully compatible with CS83711.

IU8373E is a 12V adapter power supply application for dual lithium battery series application, with two anti-breaking sound modes, spread spectrum module, built-in BOOST boost module, R class stereo audio power amplifier. It can provide a constant power of up to 2×17W@THD+N=1% for a 4Ω load. IU8373E provides the greatest convenience for the amplifier design of the audio subsystem and the cost reduction and replacement of terminal products.

The fully differential architecture and extremely high PSRR of IU8373E effectively improve the ability of IU8373E to suppress RF noise. The filter-free PWM modulation structure and built-in BOOST boost module, as well as the proprietary AERC (Adaptive Edge Rate Control) technology of IU8373E, greatly reduce the interference of EMI within the full bandwidth of audio. For a 60cm audio line, it has a margin of more than 20dB under the FCC standard. In addition, IU8373E has built-in over-current protection, short-circuit protection and over-temperature protection, which effectively protects the chip from being damaged under abnormal working conditions.
IU8373E provides a small EQA28 package for customers to choose, and its rated operating temperature range is -40℃ to 85℃.
