The LM4876M is a mono Class AB audio amplifier designed for low-voltage applications. Delivering up to 1.5W into an 8Ω load, it operates from 2V to 5.5V, making it ideal for battery-powered portable devices. Its surface-mount 8-SOIC package enables compact designs in Bluetooth speakers, radios, intercoms, and alarm systems. With built-in thermal protection and low quiescent current, the LM4876M offers reliable, high-quality audio amplification for space-constrained projects.
- High Output Power: Delivers 1.5W into 8Ω, ensuring loud and clear audio for portable speakers.
- Wide Voltage Range: Operates from 2V to 5.5V, compatible with single-cell batteries and USB power.
- Compact Package: 8-SOIC surface-mount design saves board space in dense layouts.
- Thermal Protection: Built-in shutdown and thermal protection enhance reliability in demanding conditions.
- Low Distortion: Class AB architecture provides low total harmonic distortion for clean sound reproduction.
Portable Bluetooth Speaker
The LM4876M's 1.5W output into 8Ω and 2V-5.5V supply range make it ideal for compact, battery-powered Bluetooth speakers requiring clear audio with minimal power consumption.
AM/FM Radio
Its low quiescent current and wide voltage range allow the LM4876M to drive small speakers in portable AM/FM radios, ensuring efficient operation from a single Li-ion cell.
Intercom System
With its mono output and thermal protection, the LM4876M is well-suited for intercoms where reliable, moderate-power audio amplification is needed in a compact footprint.
Alarm Driver
The LM4876M can drive piezo buzzers or small speakers in alarm systems, providing sufficient volume while operating from low-voltage backup batteries.
DIY Audio Projects
Hobbyists can use the LM4876M in simple audio amplifier circuits due to its easy-to-use 8-SOIC package, minimal external components, and stable performance over temperature.
Line Driver for Headphones
Although mono, the LM4876M can serve as a line driver for single-channel audio signals in test equipment or signal distribution, thanks to its low distortion and wide bandwidth.
