5 / 59 page STA538 Introduction 5/59 1 Introduction The STA538 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 STA538 also provides output capabilities for FFXTM. In conjunction with a power device, the STA538 provides high-quality digital amplification. The STA538 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 STA538 to work without external LC filters and without a heatsink. The STA538 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 STA538 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. Figure 1.
