illustrate

The unity-gain stabilization LM4916 is both a mono differential output (bridged load or BTL) audio amplifier and a single-ended (SE) stereo headphone amplifier. Operating from a single 1.5V supply, a mono BTL mode of 8 85mW is provided Load at 1% THD + N. In single-ended stereo headphone mode, the amplifier solution can be 16 to 14MW per channel Load at 1% THD + N.

With the LM4916 packaged in MM and LLP packages, customer benefits include low profile and small size. These packages reduce PCB area and maximize output power.

The LM4916 features circuitry that reduces the device's output transients ("click" and "snap") on and off, externally controlled low power consumption, low-level effective shutdown mode, and overheating shutdown. Boomer audio power amplifiers are designed to use very few external components and provide high-quality output power in a surface mount package.
