Bluetooth is playing an increasingly important role in modern life, and with the launch of the new generation Bluetooth audio technology standard - low-power audio LE Audio - by the Bluetooth Technology Alliance, the status of Bluetooth audio in consumer applications has been further enhanced. In this context, Dalian Lianda Quanding has launched a Bluetooth power amplifier solution based on the Qualcomm QCC5181 chip. It not only meets the BT5.4 LE Audio requirements, but also has the ability to support APTX Apactive 24bit/96kHz and Lossless high-resolution audio and multiple audio formats. Combining this solution with high-quality speakers can provide users with a high-quality audio experience.

This solution consists of four parts: a Bluetooth module, a power module, a digital to analog conversion module, and a power amplifier module. Among them, the Qualcomm QCC5181 used in the Bluetooth module is an ultra-low power single chip audio platform that can save power and improve connection reliability. QCC5181 has the ability to support multiple audio formats. Users can output various types of audio signals from audio devices that support aptx Apactive, and then connect to QCC5181 through Bluetooth to obtain high-resolution audio, enjoying a lossless high-quality audio experience.
In the audio output section, this plan uses SPDIF to transmit digital signals. Compared to analog audio signals, it is less susceptible to noise interference and can maximize the quality and stability of audio. QCC5181 provides up to 21 GPIOs and can support SPI/I ² C. UART, SPDIF, and digital microphone transmission methods.

QCC5181 provides flexible audio output. In addition to the aforementioned output methods, the chip is also equipped with Stereo analog differential output. External Differential to Single Ended lines can provide single ended analog audio output, which can adapt to different usage scenarios and requirements. Thanks to the high performance of QCC5181, this solution achieves wireless connection input and provides a high-resolution audio source through Bluetooth technology, simplifying the design process and making it an ideal choice for high-quality Bluetooth power amplifier devices.
