1 / 13 page LM4875 750 mW Audio Power Amplifier with DC Volume Control and Headphone Switch General Description The LM4875 is a mono bridged audio power amplifier with DC voltage volume control. The LM4875 is capable of deliv- ering 750mW of continuous average power into an 8 Ω load with less than 1% THD when powered by a 5V power supply. Switching between bridged speaker mode and headphone (single ended) mode is accomplished using the headphone sense pin. To conserve power in portable applications, the LM4875’s micropower shutdown mode (I Q = 0.7µA, typ) is activated when less than 300mV is applied to the DC Vol/SD pin. Boomer audio power amplifiers are designed specifically to provide high power audio output while maintaining high fidel- ity. They require few external components and operate on low supply voltages. Applications n GSM phones and accessories, DECT, office phones n Hand held radio n Other portable audio devices Key Specifications j PO at 1.0% THD+N into 8 Ω 750mW (typ) j PO at 10% THD+N into 8 Ω 1W (typ) j Shutdown current 0.7µA(typ) j Supply voltage range 2.7V to 5.5V Features n Precision DC voltage volume control n Headphone amplifier mode n “Click and pop” suppression n Shutdown control when volume control pin is low n Thermal shutdown protection Typical Application Connection Diagram Small Outline Package (SO) Mini Small Outline Package (MSOP) 10104202 Top View Order Number LM4875M, LM4875MM See NS Package Number M08A, MUA08A BOOMER™ is a trademark of National Semiconductor Corporation. 10104201 FIGURE 1.
