CXAR41288 is a stereo output-free class d audio power amplifier with ultra-low EMI and anti-clipping distortion function. it outputs up to 3.3W of power under the conditions of power supply voltage 5V, THD + N = 10% and 4Ω load, maintaining high efficiency in various audio terminal applications and providing high fidelity and low noise performance of class AB amplifier.
AROC radiation and conducted interference suppression circuit enable the CXAR41288 to have excellent full bandwidth and low radiation performance. The radiation level when the output horn line is 20cm long without auxiliary filter design is far below FCC Part15 Class B standard.
The CXAR41288's anti-clipping feature detects and suppresses output clipping distortion (broken sound) caused by excessive amplitude of music and voice signals or a drop in battery voltage, significantly improving sound quality, creating comfortable listening enjoyment and protecting speakers from overload damage. The sound quality and output power of the amplifier can be flexibly set by externally connecting different resistor and capacitor values at the ACRC end. At the same time, the chip provides ACF Off mode.
The CXAR41288 output eliminates the need for a filter network, and minimal external components save system space and cost, making it ideal for portable applications.
In addition, the built-in shutdown function is CXAR41288 to minimize standby current. It also integrates mute function, independent shutdown of left and right channels, over-current protection at speaker output, on-chip over-temperature protection and under-voltage abnormal protection. Lead-free TSSOP-20 and SOP-16 package are adopted.
