description  
The TPA4861 is a bridge-tied load (BTL) audio power amplifier capable of delivering 1 W of continuous average  
power into an 8-load at 0.2% 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 the amplifier are a shutdown function for power-sensitive applications as well as internal thermal  
and short-circuit protection. The TPA4861 works seamlessly with TI’s TPA4860 in stereo applications. The  
amplifier is available in an 8-pin SOIC surface-mount package that reduces board space and facilitates  
automated assembly.
