TPA2013D1 - Texas Instruments

TPA2013D1 2.7-W Constant Output Power Class-D Audio Amplifier

The TPA2013D1 device is a high efficiency Class-D audio power amplifier with an integrated boost converter. It drives up to 2.7 W (10% THD+N) into a 4-Ω speaker. With 85% typical efficiency, the TPA2013D1 helps extend battery life when playing audio. The built-in boost converter generates the voltage rail for the Class-D amplifier. This provides a louder aud.
