Description
The AK5705 is a high-performance four-channel 32-bit analog-to-digital converter (ADC) suitable 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 offers a dynamic range of 109[dB]. 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. The AK5705 supports sampling frequencies up to 384[kHz] and can support up to 16-channel microphone arrays by connecting multiple AK5705s.
