The TPA2080D1 device is a high-efficiency Class-D audio power amplifier with an integrated Class-G boost converter that enhances efficiency at low output power. It drives up to 2.2 W into an 4-Ω speaker (1% THD+N). With 85% typical efficiency, the TPA2080D1 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. During low audio output power periods, the boost converter deactivates and connects VBAT directly to the Class-D amplifier supply, PVDD. This improves overall efficiency.

The TPA2080D1 has an integrated low-pass filter to improve the RF rejection and reduce DAC out-of-band noise, increasing the signal-to-noise ratio (SNR).

The TPA2080D1 is available in a space-saving 1.53-mm × 1.982-mm, 0.5-mm pitch WCSP package (YZG).
