1 Introduction
1.1 Description
The TPA2026D2 is a stereo, filter-free Class-D audio power amplifier with automatic gain control (AGC),
dynamic range compression (DRC) and I
2
C™ digital volume control. The AGC and DRC functions
enhance the perceived audio loudness, and at the same time prevent speaker damage from overdrive.
The TPA2026D2 has independent software shutdown control for each channel and a 30-step volume
control. Availability in the WCSP package makes TPA2026D2 an ideal choice for both cellular handsets
and PDAs.
The TPA2026D2 evaluation module (EVM) is a complete, stand-alone audio board. It contains the
TPA2026D2 WCSP (YZH) Class-D audio power amplifier.
All components and the EVM are Pb free.
