Product Summary
The TPA4861DR is a bridge-tied load (BTL) audio power amplifier capable of delivering 1 W of continuous average power into an 8-Ω load at 0.2% 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 TPA4861DR are a shutdown function for power-sensitive applications as well as internal thermal and short-circuit protection. The TPA4861DR is available in an 8-pin SOIC surface-mount package that reduces board space and facilitates automated assembly.
