AKM Semiconductor, Inc. Digital to Analog Converters (DAC) AK4367VN

The AK4367VN is a low power 24-bit digital to analog converter (DAC) designed for mobile and portable communication applications. It features a built-in headphone amplifier capable of delivering 50mW per channel at 16,Ѷ, with a signal-to-noise ratio of 92dB at 2.4V. The DAC supports a sampling rate range of 8kHz to 48kHz and includes a digital de-emphasis filter for 32kHz, 44.1kHz, and 48kHz audio formats. This device incorporates an analog mixing circuit, making it suitable for applications requiring audio output mixing. It operates with a power supply voltage between 2.2V and 3.6V, consuming 2.8mA at 2.4V when the headphone amplifier is not in use. The AK4367VN is housed in a compact 20-pin QFN package, which is advantageous for space-constrained designs. The device also features pop noise-free power-on/off and mute controls, enhancing user experience in audio applications.
