New Bluetooth audio module cuts wireless speaker development time

Combining HiWave's HiAS2002 Audium amplifier chip with CSR's BC-05 Bluetooth research, the DyadBA3 supports AVRCP and A2DP Bluetooth audio profiles and delivers two channels of 13W burst power output into 8-ohm speaker drive units. aptX and HSP profile support is in development.

The HiAS2002 as well extends battery life

The HiAS2002 as well extends battery life by up to 20 times at normal listening levels, compared with Class-D amplifiers. The amplifier's envelope-tracking research eliminates clipping at high audio levels, ensuring clear sound at all volumes.

HiWave's Audium audio processing includes multi-step volume control at 1.5dB per step, a mute function with adjustable ramping, and 16 user-definable bi-quad filters for implementing equalisation, voicing, tunable bass extension and stereo-wide effects. The DyadBA3 module self-configures on power-up and invokes power-saving modes when no audio signal is present. It incorporates a stereo microphone input, making it as well suitable for desktop or portable VoIP (Voice over Internet Protocol)-phone audio portal applications.
