TPA2015D1 (ACTIVE) 2W Mono Analog Input Class-D Speaker Amp with Integrated Class-G Boost Converter

 

Description

The TPA2015D1 is a high efficiency Class-D audio power amplifier with battery-tracking SpeakerGuard AGC technology and an integrated adaptive boost converter that enhances efficiency at low output power. It drives up to 2 W into an 8 Ω speaker (6% THD). With 85% typical efficiency, the TPA2015D1 helps extend battery life when playing audio.

The built-in boost converter generates a 5.5 V supply voltage for the Class-D amplifier. This provides a louder audio output than a stand-alone amplifier directly connected to the battery. The SpeakerGuardTM AGC adjusts the Class-D gain to limit battery current and prevent heavy clipping.

The TPA2015D1 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 TPA2015D1 is available in a space saving 1.954 mm × 1.954 mm, 0.5 mm pitch DSBGA package (YZH).
