description  
The TPA4860 is a bridge-tied load (BTL) audio power amplifier capable of delivering 1 W of continuous average  
power into an 8-Ω load at 0.4 % THD+N from a 5-V power supply in voiceband frequencies (f < 5 kHz). A BTL  
configuration eliminates the need for external coupling capacitors on the output in most applications. Gain is  
externally configured by means of two resistors and does not require compensation for settings of 2 to 20.  
Features of this amplifier are a shutdown function for power-sensitive applications as well as headphone  
interface logic that mutes the output when the speaker drive is not required. Internal thermal and short-circuit  
protection increases device reliability. It also includes headphone interface logic circuitry to facilitate headphone  
applications. The amplifier is available in a 16-pin SOIC surface-mount package that reduces board space and  
facilitates automated assembly.
