Frequently Asked Questions
What is the output power of the LM4879SDX/NOPB?
The LM4879SDX/NOPB delivers a nominal output power of 1.2 W, which is appropriate for driving small speakers in compact portable audio devices. This power level makes it well-suited for handheld consumer electronics, personal media players, and portable wireless speakers operating from a single-cell lithium battery.
What package does the LM4879SDX/NOPB use and how many pins does it have?
The LM4879SDX/NOPB uses an 8-pin Small Outline No-Lead (SON) package, designated JEDEC code S-PDSO-N8. The SON package has a very small footprint with exposed pad thermal dissipation, enabling compact PCB layouts and improved heat management compared to standard SOIC packages of equivalent pin count.
Is the LM4879SDX/NOPB RoHS compliant?
Yes, the LM4879SDX/NOPB is RoHS compliant. The '/NOPB' suffix confirms the lead-free, no-lead-plating construction, verified by Pbfree Code 'Yes' and JESD-609 Code 'e3'. This makes it compatible with RoHS-restricted product applications in the European Union, China, and other regulatory jurisdictions worldwide.
How many audio channels does the LM4879SDX/NOPB support?
The LM4879SDX/NOPB is a single-channel (mono) audio amplifier. It contains one amplification function, making it ideal for mono speaker applications such as alert tones, voice prompts, or mono audio playback in portable devices. For stereo output, two devices would need to be used in parallel or a stereo amplifier IC should be selected.
What are typical applications for the LM4879SDX/NOPB?
The LM4879SDX/NOPB is commonly used in MP3 players, portable gaming consoles, mobile phones, and small consumer electronics requiring a compact mono audio amplifier. Its low quiescent current and efficient operation make it suitable for battery-powered designs. It also applies to intercom systems, electronic toys, and IoT devices with audio notification features.
