LM4916 - 14mW Stereo Headphone Audio Amplifier

General Description

The unity gain stable LM4916 is both a mono differential output (for bridge-tied loads or BTL) audio power amplifier and a Single Ended (SE) stereo headphone amplifier.

Operating on a single 1.5V supply, the mono BTL mode delivers 85mW into an 8Ω load at 1% THD+N.

Key Features

  • 1.
  • 2 Single-Cell 0.9V to 2.5V Battery Operation.
  • BTL Mode for Mono Speaker.
  • Single-Ended Headphone Operation with Coupling Capacitors.
  • Unity-Gain Stable.
  • "Click and Pop" Suppression Circuitry.
  • Active-Low Micropower Shutdown.
  • Low Current, Active-Low Mute Mode.
  • Thermal Shutdown Protection Circuitry.
