Product details

Output power and load matching

The LM4875MX/NOPB: The 1W into 8Ω rating handles a small speaker for voice or alert tones; the 110mW into 32Ω covers consumer headphone levels.

Temperature grade and environment

Rated -40°C to 85°C ambient, the LM4875MX/NOPB suits industrial-temperature environments — outdoor telecom panels, factory-floor audio indicators, or automotive cabin modules (non-AEC). The 8-SOIC package reflows onto standard FR4; keep the thermal pad (if present) soldered to a copper pour for heat spreading at 1W continuous output.

Frequently asked questions

Can LM4875MX/NOPB be used as a direct replacement for LM4875M?

The LM4875MX/NOPB is the ROHS3-compliant, tape-and-reel variant of the LM4875M. Pinout and electrical specifications are identical, so it serves as a drop-in replacement in most designs. Verify the package marking and solder profile for the lead-free finish.

What are the typical applications for LM4875MX/NOPB?

Typical applications include portable speakers, headphone amplifiers, voice annunciators, and battery-powered audio devices that need a mono output up to 1W into an 8Ω load.

Does LM4875MX/NOPB have thermal shutdown protection?

Yes, thermal protection is one of the integrated features, along with depop, mute, shutdown, and volume control.
