Asahi Kasei Microdevices Corporation, (AKM), has developed a 32-bit mono portable audio DAC with a built-in headphone amplifier optimized for true wireless earphones, (TWS: True Wireless Stereo).
The AK4332ECB supports both high quality sound and ultra-low power consumption, integrated into an ultra-small 30-pin CSP package. Mass production of the AK4332ECB is scheduled for the summer of 2019.
VELVET SOUND technology is optimized in pursuing high quality sound and high performance for TWS. The AK4332ECB achieves high performance of -101dB THD+N and 109dB SNR with the industry's most advanced level of ultra-low power consumption at 2.8 mW. This will enable TWS playback for long times with high quality sound.
Further low power consumption is achieved by executing digital signal processing of the digital filtering and ΔΣ modulation with a Bluetooth SoC which utilizes small geometry transistors.
