Texas Instruments LM48310 Ultra-Low EMI, Filterless, 2.6W, Mono, Class D Audio Power Amplifier with E2S LM48310SD/NOPB

The LM48310SD/NOPB is a mono, Class D audio power amplifier designed for portable multimedia devices, capable of delivering 2.6W of output power to a 4,Ѷ load with less than 10% total harmonic distortion plus noise (THD+N). It operates from a single supply voltage ranging from 2.4V to 5.5V, making it versatile for various applications. The amplifier features an Enhanced Emissions Suppression (E¬=S) system that significantly reduces electromagnetic interference (EMI) while maintaining audio quality and efficiency, achieving a typical efficiency of 88% at 5V and 1W output into an 8,Ѷ load. The device includes built-in output short circuit protection with auto-recovery, low power shutdown mode, and click and pop suppression to enhance user experience. It is internally configured for a gain of 12dB, which minimizes the need for external components. The LM48310 also supports synchronization for multi-channel operation, allowing multiple devices to operate at the same switching frequency, thus reducing beat frequencies and interference. It is packaged in a compact WSON format, suitable for space-constrained designs, and operates within a temperature range of -40¬8C to 85¬8C.
