Introduction

The STA330 is a digital stereo audio processor with analog and digital input. It includes an

audio DSP and FFX, a ST proprietary high-efficiency class-D driver. In conjunction with a

power device, the STA330 provides high-quality digital amplification.

The STA330 contains an on-chip volume/gain control.

The PWM amplifier achieves greater than 90% efficiency for longer battery life for portable

systems.

The STA330 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 STA330 is designed for low-power operation with extremely low-current consumption in

standby mode. It is available in the package VFQFPN52, a very thin (1.2 mm thick) package

that can be used for small portable applications.
