As AKM explains, this is not a premium audio Velvet Sound type product but a new developer-friendly alternative that is ideal for general consumer electronics, particularly wearable devices, augmented reality/virtual reality design (AR/VR), microphone array systems, and even more commercial and industrial applications, IC recorders, etc.
The new AK5705 is a high-performance four-channel 32-bit analog-to-digital converter (ADC) that is valuable for audio, voice recognition, voice control, and teleconferencing applications. The AK5705's low-noise, low-power microphone amplifier is suitable for high S/N microphone applications and is connectable with current output devices. The built-in transimpedance amplifier for current-to-voltage conversion allows the output current of a sensor or photodiode to be converted to digital data.
As AKM details, the AK5705 supports sampling frequencies up to 384kHz, can be combined with wideband microphones, and can support up to 16-channel microphone arrays by connecting multiple AK5705s. Built-in AC coupling capacitors significantly reduce the mounting area and the number components required for analog inputs, so systems can be built with fewer external components.
Asahi Kasei Microdevices (AKM) operates the electronic components business as a member of the Asahi Kasei Group's material sector. AKM’s audio A/D converters (ADCs) and D/A converters (DAC) are IC solutions for high quality audio systems, contributing to power consumption improvements and reducing external parts.
The AK5705 is available in a wafer-level chip scale packaging (WLCSP). Samples are currently provided and its sale will commence in the fourth quarter of 2023.
