1 / 21 page  LM4875 www.ti.com SNAS042C – JANUARY 2002 – REVISED MAY 2013 LM4875 750 mW Audio Power Amplifier with DC Volume Control and Headphone Switch Check for Samples: LM4875 1 FEATURES DESCRIPTION The LM4875 is a mono bridged audio power amplifier 2 • Precision DC Voltage Volume Control with DC voltage volume control. The LM4875 is • Headphone Amplifier Mode capable of delivering 750mW of continuous average • “Click and Pop” Suppression power into an 8 Ω load with less than 1% THD when powered by a 5V power supply. Switching between • Shutdown Control When Volume Control Pin Is bridged speaker mode and headphone (single ended) Low mode is accomplished using the headphone sense • Thermal Shutdown Protection pin. To conserve power in portable applications, the LM4875's micropower shutdown mode (IQ = 0.7µA, APPLICATIONS typ) is activated when less than 300mV is applied to the DC Vol/SD pin. • GSM Phones and Accessories, DECT, Office Phones Boomer audio power amplifiers are designed specifically to provide high power audio output while • Hand Held Radio maintaining high fidelity. They require few external • Other Portable Audio Devices components and operate on low supply voltages. KEY SPECIFICATIONS • PO at 1.0% THD+N Into 8Ω; 750 mW (typ) • PO at 10% THD+N Into 8Ω; 1 W (typ) • Shutdown Current; 0.7µA(typ) • Supply Voltage Range; 2.7V to 5.5 V TYPICAL APPLICATION CONNECTION DIAGRAM Small Outline Package (SOIC) Mini Small Outline Package (VSSOP) Top View See Package Number D, DGK Figure 1.
