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