The AK5704EN from Asahi Kasei Microdevices is a specialized analog front-end ADC IC ideal for applications such as voice recognition, voice control, and conferencing. It features a built-in 4-channel, 32-bit ADC coupled with a low-noise microphone amplifier, capable of extracting full performance from high S/N microphones while maintaining low power consumption.
Key electrical specifications include a dynamic range of 105dB and a THD+N of 90dB at 0dB gain. The device supports single-ended or full-differential inputs and offers MIC amplifier gain adjustable in 3dB steps from +30dB to 0dB. It operates over a temperature range of -40°C to 85°C and supports a wide operating voltage range of 1.7V to 3.6V for analog supplies and 1.65V to 3.6V for digital supplies.
The AK5704EN supports various digital audio interfaces, including I2S, MSB justified, and PCM, with sampling frequencies up to 192kHz. It also incorporates an ultra-low power voice activity detector, significantly reducing power consumption during wait times. The device is housed in a compact 28-pin QFN package, suitable for surface mounting.
