Linkplay Technology Announces New WiiM Pro Plus with Premium DAC Built-in

Linkplay Technology launched the WiiM Pro Plus, an upgraded version of its successful WiiM Pro audio streamer. Listening to the market, the new WiiM Pro Plus now offers a premium AKM DAC built-in, and takes home audio to a new level featuring enhanced audio-quality, all within the same simple and cost-effective package. The WiiM Pro Plus is designed to reduce the total system cost, allowing music enthusiasts to create a high-res streaming audio system that extends existing equipment, for a fraction of the cost of buying a new setup, additional cables or an external DAC.

Asahi Kasei Microdevices (AKM) has developed the AK5705, a low power consumption 4-channel 32-bit A/D converter (ADC) with a built-in transimpedance amplifier in addition to a low-noise microphone amplifier. The new AKM the AK5705 ADC is connectable to current output sensors, supports a sampling frequency of 384kHz, and achieves a dynamic range of 109dB, while consuming 43% less power than existing AKM products. The built-in AC coupling capacitor significantly reduces the mounting area including external components.

Asahi Kasei Microdevices Corporation (AKM) has developed and started the release of samples of the AK7749, an in-vehicle DSP-integrated CODEC with an automatic mode switching function to support voice applications, and a full range of digital and analog input/output interfaces. The AK7749 is a RAM based, highly integrated, programmable digital signal processor, with 4 channel ADCs, 2 channel DACs, a MIC gain amplifier, a line-out amplifier, 4 channel SRCs, and digital audio I/F, all in a space saving small 48-pin QFN package.
