Product Overview
LM4875MX/NOPB is a low-voltage Texas Instruments mono audio amplifier designed for portable and compact speaker applications. Its bridged output removes the need for a large output coupling capacitor while producing up to approximately 750 mW into an 8 Ω load from a 5 V supply under the datasheet test condition.
Integrated DC volume control, headphone mode and shutdown simplify the surrounding audio path.

Speaker-Drive Considerations
The headline power is tied to a 5 V supply and the specified distortion/load condition. Lower supply voltage, higher speaker impedance or limited PCB thermal dissipation will reduce available continuous power.
