Overview
The LM4875 is a mono bridged audio power amplifier with DC voltage volume control. The LM4875 is capable of delivering 750mW of continuous average power into an 8Ω 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 (IQ = 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 fidelity. They require few external components and operate on low supply voltages.
Applications
- GSM Phones and Accessories

Key features
- Precision DC Voltage Volume Control
- Headphone Amplifier Mode
- “Click and Pop” Suppression
- Shutdown Control When Volume Control Pin Is Low
- Thermal Shutdown Protection
