Bluetooth® Audio SoC
Actions Bluetooth® headset chip series products are mainly dual-mode Bluetooth® 5.4 single-chip solutions, featuring high sound quality, low latency, and low power consumption. They are mainly used in the true wireless stereo headset (TWS), neck-mounted headsets, headphones, and other wearable audio devices. Actions Technology specializes in providing high-quality and low-latency wireless audio experience under the premise of low power consumption. The series of products have Bluetooth® transmission power up to 13dBm and the receive sensitivity is -96dBm, which effectively improves the stability of the audio connection. In the case of playing normal music, the no-load power consumption is as low as 4.xmA. 20 bands of audio PEQ, support music and call scene sound adjustment. Support dual connection, connects any two Bluetooth® devices at the same time, which it is easy to switch. With low latency mode, that makes Bluetooth® audio signal delay in low-latency mode as low as 50ms, users can enjoy high-fidelity sound at lower latency. In addition, owns single and dual microphone call AI noise reduction algorithm which greatly improves the users' call experience.
Now the main Bluetooth® headset chips are ATS3015E、ATS3015S、ATS3019E、ATS3025、ATS3039.
