The TPA4861 is a bridged load (BTL) audio power amplifier that provides 1 to 8 consecutive average power watt capability -At 0.2% THD+N load from a 5 V power supply, the spoken audio band frequency (vi The BTL configuration eliminates the need for output for most applications on an external coupling capacitor. The gain is configured with two external resistors and does not require compensation from 2 to 20. The amplifier functions as shutdown function for power-sensitive applications and internal overtemperature and short-circuit protection. Works seamlessly with TI's TPA4861 in stereo application TPA4860. The amplifier is available in an 8-pin SOIC surface mount package that reduces board space and facilitates automated assembly.
