TPA2015D1 2W Class-D Audio Amplifiers Texas Instruments TPA2015D1 2W Class-D Audio Amplifiers offer high efficiency with battery-tracking SpeakerGuard™ AGC technology and an integrated adaptive boost converter that improves efficiency at low output power. The TPA2015D1 drives up to 2W into an 8Ω speaker (6% THD) and has an 85% typical efficiency to extend battery life when playing audio. The built-in boost converter develops a 5.5V supply voltage for the TPA2015D1 amplifier, supplying a louder audio output than a stand-alone amplifier directly connected to the battery. The SpeakerGuard AGC adjusts the Class-D gain to limit battery current and prevent heavy clipping.
