3 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).
