The AK4458VN is a 32-bit 8-channel premium digital-to-analog converter (DAC) from Asahi Kasei Microdevices (AKM), part of their VELVET SOUND architecture. It supports PCM input up to 768kHz and DSD input up to 11.2MHz, making it suitable for high-resolution audio playback.
Key electrical specifications include a signal-to-noise ratio of 115dB, total harmonic distortion plus noise of -107dB, and differential analog output. The device operates from analog supply voltage of 3.0V to 5.5V and digital supply voltage of 1.7V to 3.6V. It features five selectable 32-bit digital filters with options like sharp roll-off and slow roll-off.
The AK4458VN is housed in a 48-pin HVQFN package (48-QFN 7x7mm) with exposed pad for thermal management. It supports multiple data interfaces including I2S, DSD, and TDM, and can be configured in daisy chain for multi-channel applications. Operating temperature range is -40°C to 105°C.
Typical applications include AV receivers, CD/SACD players, network audio players, USB DACs, sound bars, car audio systems, and measurement equipment.
The AK4458VN requires an analog supply voltage (AVDD) of 3.0V to 5.5V and a digital supply voltage (TVDD) of 1.7V to 3.6V.
