The TPA301 is a bridged load (BTL) audio power amplifier that is especially useful for developing applications that require low voltages in internal speakers. Powered by a 3.3-V supply, it is capable of providing a continuous output power of 8 250 MW under the TPA301 line.Less than 1% of THD+N loads the entire language band. Although this device is characterized by going out to 20 kHz, its operation is optimized for narrow-band applications such as mobile communications. The BTL configuration eliminates the output to most applications on externally coupled capacitors, which is an important requirement especially for small battery-powered devices. The device has a power sensitive application shutdown mode with zero quiescent current.
