What is LM4910MM used for?
The LM4910 is a compact stereo headphone amplifier designed for portable consumer electronics including MP3 players, handheld gaming devices, and personal digital assistants requiring low-power audio output. Its 35 mW per channel output power from a 3V to 5V supply suits 32-ohm headphone loads, while the low quiescent current extends battery life in always-on audio applications. The tiny TSSOP-8 package integrates smoothly into space-constrained PCB designs alongside audio codecs and DSP chips.

Frequently Asked Questions
What is the output power of the LM4910MM per channel, and at what supply voltage?
The LM4910MM delivers 35 mW per channel into a 32-ohm headphone load at a 3V supply with less than 0.1% THD+N. This output level is sufficient for comfortable listening volume through standard stereo headphones in portable MP3 players and handheld audio devices.
Can the LM4910 drive both headphones and small speakers in a portable design?
The LM4910 supports both single-ended headphone outputs and BTL (bridge-tied load) configuration. In BTL mode, bridging two channels across an 8-ohm speaker load effectively doubles available voltage swing, providing up to 4x the power into a speaker compared to single-ended headphone mode, enabling small speaker drive from the same IC.
What package does the LM4910MM use, and how small is its PCB footprint?
The LM4910MM uses an 8-pin TSSOP package with 0.65 mm pin pitch and a body measuring approximately 3 mm x 4.4 mm, making it one of the smallest available stereo audio amplifier footprints. This compact size is compatible with high-density PCB designs in wearables, portable media players, and IoT audio devices.
Does the LM4910 include pop-and-click suppression for user-friendly audio applications?
The LM4910 incorporates internal pop-and-click suppression circuitry that manages output ramp-up and ramp-down during power transitions. This eliminates the loud audible transient that would otherwise occur when powering on or off headphone-connected devices, improving the user experience without requiring external RC time-constant circuits.
For a battery-powered device running from 2xAA cells, is the LM4910 supply range compatible?
Two fully-charged AA alkaline cells provide approximately 3V, matching the LM4910's minimum operating supply of 2.7V. As the batteries discharge toward 2V, the LM4910 maintains operation down to its lower supply limit, extending usable battery life while the 35 mW output power gradually scales with supply voltage.
