Acoustic Technologies Introduces the ATH3001 IC for Hands-Free Car Kits

MESA, Ariz. - Acoustic Technologies introduced the ATH3001 Hands-Free Car Kit full-duplex integrated circuit for improved sound quality in hands-free applications. The SoundClearÃ’ enabled ATH3001 provides improved speech intelligibility with high speaker volume in noisy car environments. Signal integrity and improved sound quality are achieved through the Acoustics' SoundClear suite of technology and full-duplex control that dynamically monitors, detects and processes incoming voice, echo and noise signal power levels. The echo cancellation technology is robust to automotive background noise environments and mobile phone network imperfections.


The ATH3001 feature list includes 42dB acoustic echo cancellation, 30dB network echo cancellation, up to 12dB noise reduction, 10-band graphic equalizer and sound enhancement. For ease of system integration, the ATH3001 includes dual analog CODECs, a microphone preamp and an output speaker driver. There is an additional digital PCM interface for simple connection to Bluetooth or other digital interfaces. Integrated monitoring and control processors with noise management ensure clear two-way communication. The ATH3001 device reduces component count and hands-free car kit system cost by providing integrated CODECs and advanced I/O ports.
