Introduction

Introduction
The STA529 is a digital stereo class-D audio amplifier. It includes an audio DSP, a ST
proprietary high-efficiency class-D driver and CMOS power output stage. It is intended for
high-efficiency digital-to-power-audio conversion for portable applications. The STA529 also
provides output capabilities for FFXTM. In conjunction with a power device, the STA529
provides high-quality digital amplification.
The STA529 contains an on-chip volume/gain control.
The PWM amplifier achieves greater than 90% efficiency for longer battery life for portable
systems.
The innovative class-D modulation, allows the STA529 to work without external LC filters
and without a heatsink.
The STA529 I2CDIS pin disables the audio DSP functions to provide a direct conversion of
the input signal into output power (the I2C interface is disabled). This conversion is done
without the microcontroller.
The STA529 is designed for low-power operation with extremely low-current consumption in
standby mode. It is available in two packages: the TFBGA48 and the VFQFPN52. These are
very thin packages (1.2 mm thick) intended for small portable applications.
