AK4495S/95
Quality-oriented Premium 32-Bit 2ch DAC
1. General Description
The AK4495S/95 is a 32-bit DAC, which corresponds to high-performance, high sound quality digital audio
systems such as DVD-Audio and BD. An internal circuit includes newly developed 32-bit digital filters for
better sound quality, achieving low distortion characteristics and wide dynamic range. The AK4495S/95 has
full differential SCF outputs, removing the need for AC coupling capacitors and increasing performance for
systems with excessive clock jitter. The AK4495S/95 accepts up to 768kHz PCM data and 5.6MHz DSD data,
ideal for a wide range of applications including Network Audio and SACD.
