The integrated component is ideal for small application designs powered by a single-voltage supply and with embedded audio system designs. The TLV320AIC23BI is designed to meet the increasing demand in the automotive, consumer media and communications industries for high-performance audio solutions with enhanced power management and control.

Application Field

The TLV320AIC23BIPWR is an integrated audio system with integrated digital audio interface, high-definition audio CODEC and power management, which is applicable for a variety of interface applications. The component is ideal for use in automotive applications, such as car audio and vehicle infotainment systems. It is also applicable for handheld devices and consumer entertainment products, including game consoles, MP3 players and personal media players. The component provides a complete audio solution, including speakers, microphones, line-in and line-out.

Working Principle

The TLV320AIC23BIPWR component uses a three-level power management system that allows for reduced power consumption and increased efficiency. The component operates in three different power modes; Active, Idle and Sleep. In the Active mode, the component is enabled and all its features can be used. The idle mode reduces the power consumption of the component by disabling the digital audio interface. The Sleep mode reduces the power consumption further by disabling the audio CODEC and all its associated features.The component also includes a Serial Audio Interface (SAI) for digital audio data transfers. The SAI is a two-channel, asynchronous serial audio processing interface that uses I2S or Left-Justified data formats. The SAI is used to transfer audio data from a digital audio source to the CODEC, and from the CODEC to a digital audio destination. Additionally, the component can be configured to operate as a Processor-Directed CODEC by using the Processor Interface Option. This allows for more efficient streaming applications by removing the need for a separate interface to control the audio parameters of the CODEC.

Conclusion

The TLV320AIC23BIPWR is an integrated audio system with integrated digital audio interface, high-definition audio CODEC and power management that provides a complete solution for a variety of interface applications. The component is ideal for use in automotive applications, such as car audio and vehicle infotainment systems, as well as a variety of consumer entertainment products. Additionally, the component can be configured to operate as a Processor-Directed CODEC for more efficient streaming applications.
