The unity gain stable LM4925 is both a mono differential output (for BTL operation) audio amplifier and a Single Ended (SE) stereo headphone amplifier. Operating on a single 3V supply, the mono-BTL mode delivers 410mW into an 8 load at 1% THD+N. In Single Ended stereo headphone mode, the amplifier delivers 40mW per channel into a 16 load at 1% THD+N.
With the LM4925 packaged in the MM and LLP packages, the customer benefits include low profile and small size. This package minimizes PCB area and maximizes output power.
The LM4925 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
