Texas Instruments LM48410 Low EMI, Filterless, 2.3W Stereo Class D Audio Pwr Amp w/ Natl 3D Enhancement LM48410SQ/NOPB

The LM48410SQ/NOPB is a low EMI, filterless, stereo Class D audio power amplifier designed for high efficiency and compact applications. It operates from a single supply voltage of 2.4V to 5.5V and delivers up to 2.3W per channel into a 4,Ѷ load with less than 10% total harmonic distortion plus noise (THD+N). The device features a low noise PWM architecture that eliminates the need for output filters, reducing the overall component count and board area. It includes selectable spread spectrum modulation to suppress RF emissions, enhancing EMI performance. The LM48410 also supports independent channel shutdown controls, logic selectable gain options, and incorporates 3D audio enhancement for improved sound quality. The amplifier is packaged in a space-saving 4mm x 4mm WQFN format, making it suitable for mobile phones, PDAs, and laptops. The device is characterized by low quiescent power consumption and high efficiency, making it a viable choice for battery-powered applications.
