Frequently Asked Questions

What output power does the LM4818MX deliver and at what supply voltage?

The LM4818MX delivers up to 350 mW of output power into a speaker load, operating from a single supply voltage typically in the 2.7 V to 5.5 V range, making it well suited for battery-powered portable consumer audio applications.

Which audio frequency range does the LM4818MX support for speaker drive applications?

The LM4818MX supports a nominal bandwidth of 20 kHz, covering the entire audible spectrum from 20 Hz to 20 kHz, with a harmonic distortion rating of 10%, making it appropriate for voice and music playback in cost-sensitive designs.

How many audio channels does the LM4818MX amplifier provide, and what package does it use?

The LM4818MX provides 1 channel (mono) audio amplification and is housed in an SOIC-8 (R-PDSO-G8) 8-pin small outline package, occupying minimal board space and simplifying PCB routing for handheld or compact electronic products.

When should a designer choose the LM4818MX over a stereo audio amplifier IC?

A designer should choose the LM4818MX when only a single speaker channel is required, such as in alarm modules, intercoms, or mono speaker systems, where the 350 mW output power and 8-pin SOIC footprint provide sufficient performance at lower cost and smaller board area than stereo alternatives.
