Texas Instruments TPA2025D1YZGR

The TPA2025D1 is a high efficiency Class-D audio power amplifier with battery tracking AGC technology and an integrated Class-G boost converter that enhances efficiency at low output power. It drives up to 1.9 W into an 8-Ω speaker (1% THD+N). With 85% typical efficiency, the TPA2025D1 helps extend battery life when playing audio.

The built-in boost converter generates a 5.75-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 battery tracking AGC adjusts the Class-D gain to limit battery current at lower battery voltage.

The TPA2025D1 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 TPA2025D1 is available in a space saving 1.53 mm × 1.982 mm, 0.5 mm pitch DSBGA package (YZG).
