1 Introduction

1.1Description

The TPA2028D1 is a mono, filter-free Class-D audio power amplifier with automatic gain control (AGC), dynamic range compression (DRC) and I2C digital volume control. The AGC and DRC functions enhance the perceived audio loudness, and at the same time prevent speaker damage from overdrive. The TPA2028D1 has independent software shutdown control and a 30-step volume control. Availability in the WCSP package makes TPA2028D1 an ideal choice for both cellular handsets and PDAs.

The TPA2028D1 evaluation module (EVM) is a complete, stand-alone audio board. It contains the TPA2028D1 WCSP (YZF) Class-D audio power amplifier.

All components and the EVM are Pb free.
