We offer high-value and high-quality Bluetooth® audio silicon and module solutions. They are compliant with the latest Bluetooth specifications and are proven for interoperability. Low power and small form factor with a built-in Bluetooth stack, our audio solutions provide excellent audio quality (SNR), sound level and sound effects (DSP). They also support digital audio, a variety of audio sources and value-added features such as support for multiple speakers and high-resolution Bluetooth audio with LDAC™ technology.

The IS2064 Bluetooth audio SoC supports LDAC technology and other audio codec interfaces. Sony's LDAC audio codec technology is considered the highest-quality audio codec available. It transmits up to 990 kbps data throughput, which is three times higher than the standard Bluetooth Sub-band Codec (SBC), and maintains frequency and bit depth of up to 96 kHz/24-bit, allowing for High Resolution (Hi-Res) audio. Email BTAudio@Microchip.com for more information.
