The LM4916LDX/NOPB is a low-voltage, Class AB audio amplifier designed for portable applications requiring both mono speaker output and stereo headphone drive. Operating from just 900mV to 2.5V, it delivers 85mW into an 8Ω speaker and 14mW per channel into 16Ω headphones. Integrated features such as Depop, Mute, Shutdown, and Thermal Protection ensure clean audio, low power consumption, and reliable operation in space-constrained designs. Housed in a compact 10-WSON package, this amplifier is ideal for battery-powered devices like MP3 players, mobile phones, and portable speakers.
- Ultra-Low Voltage Operation: Operates from 900mV to 2.5V, enabling direct battery-powered use with minimal power loss.
- Integrated Audio Management: Depop, Mute, and Shutdown circuits reduce noise and extend battery life in portable devices.
- Compact Package: 10-WSON (3x3mm) with exposed pad saves board space and improves thermal dissipation.
- Dual Output Flexibility: Mono speaker drive plus stereo headphone output supports versatile audio system designs.
Portable Bluetooth Speakers
The LM4916LDX/NOPB's low supply voltage range (900mV to 2.5V) and mono output with stereo headphone capability make it perfect for compact Bluetooth speakers that need efficient power management and clear audio from a single Li-ion cell.
MP3 and Media Players
With 85mW output into 8Ω and 14mW into 16Ω headphones, this amplifier provides sufficient volume for personal media players while the Depop circuit eliminates audible clicks during power-up or shutdown.
Mobile Phone Audio Subsystems
The integrated Mute and Shutdown functions allow the LM4916 to interface seamlessly with mobile phone basebands, conserving power during idle periods and ensuring clean audio transitions.
Battery-Powered Intercoms
Its ultra-low voltage operation down to 900mV enables reliable audio amplification in intercom systems powered by a single alkaline or NiMH cell, extending battery life significantly.
Portable Gaming Consoles
The thermal protection and small 10-WSON package suit handheld gaming devices where space is limited, delivering clear mono sound for game audio and voice chat through headphones.
DIY Audio Projects
Hobbyists can leverage the LM4916's simple external component count and low voltage requirements to build custom low-power audio amplifiers for wearable electronics or small radios.
