summary

CS83705E is a Class R monophonic device suitable for dual-power supply applications powered by single or double-cell lithium batteries and 12V adapters. It has fixed gain, three anti-crack modes, AB/D switching, mute function, and built-in BOOST boost module. Audio power amplifier. When powered by two-cell lithium batteries (7.4V), the CS83705E can drive speakers as low as 2Ω and output a maximum constant power of 26W; the design of the CS83705E AB Class D switchable mode minimizes the impact of the power amplifier in the audio subsystem. FM interference provides the ultimate power output for end products.

The CS83705E's fully differential architecture and extremely high PSRR effectively improve the ability to suppress RF noise. The filter-less PWM modulation structure and built-in BOOST boost module, as well as the CS83705E's proprietary AERC (Adaptive Edge Rate Control) technology, greatly reduce EMI interference within the full audio bandwidth range, and are suitable for 60cm audio cables. , with a margin of more than 20dB under FCC standards. In addition, CS83705E has built-in overcurrent protection, short circuit protection and overheating protection, which effectively protects the chip from damage under abnormal working conditions.

CS83705E provides a small EQA16L package for customers to choose. The package size is the same as ESOP8, and its rated operating temperature range is -40℃ to 85℃.
