Audio Amp Headphone/Speaker 1-CH Mono/2-CH Stereo 0.085W Class-AB 10-Pin MSOP T/R, LM4916MM/NOPB, Texas Instruments

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 8? load at 1% THD+N. In Single Ended stereo headphone mode, the amplifier delivers 14mW per channel into a 16? load at 1% THD+N.With the LM4916 packaged in the MM and WSON packages, the customer benefits include low profile and small size. These packages minimize PCB area and maximizes output power.The LM4916 features circuitry that reduces output transients (“clicks” and “pops”) during device turn-on and turn-off, an externally controlled, low-power consumption, active-low shutdown mode, and thermal shutdown. Boomer audio power amplifiers are designed specifically to use few external components and provide high quality output power in a surface mount package.
