Product details

What this part is and where it fits

The Texas Instruments LM4853MM/NOPB is a Class AB audio amplifier from the Boomer® series, combining a 1-channel mono speaker amplifier with a separate stereo headphone output in a single 10-VSSOP package.

Output power — what the 3Ω and 8Ω ratings mean for your BOM

The 1.9W into 3Ω rating is the mono speaker channel's maximum output; the 300mW into 8Ω per channel is the headphone output.

Features that matter in a portable design

The depop circuit suppresses power-on and power-off clicks, which is a practical concern in battery-powered devices where the amplifier is frequently enabled and disabled. The shutdown pin reduces quiescent current to near zero, extending battery life during idle periods. Thermal protection prevents the IC from damaging itself under a shorted load or excessive ambient temperature — it reduces output drive rather than latching off, so audio recovers automatically when the die cools.

Frequently asked questions

What is the output power of LM4853MM/NOPB into 3Ω and 8Ω loads?

The mono speaker channel delivers 1.9W into a 3Ω load, and the stereo headphone outputs deliver 300mW per channel into an 8Ω load.

Does LM4853MM/NOPB support both mono speaker and stereo headphone outputs?

Yes, it has a 1-channel mono speaker output and a separate stereo headphone output, all in one IC.
