Texas Instruments TPA2080D1 2.2W Class-D Audio Amplifier
Texas Instruments TPA2080D1 2.2W Constant Output Power Class-D Audio Amplifier features an integrated Class-G boost converter that enhances efficiency at low output power. TI TPA2080D1 drives up to 2.2W into a 4Ω speaker (1% THD+N). With 85% typical efficiency, the TPA2080D1 Class-D Audio Amplifier helps extend battery life when playing audio. The built-in boost converter generates a 5.75 V supply voltage for the Class-D amplifier when high output power is required. This provides a louder audio output than a stand-alone amplifier directly connected to the battery.
