The AK4358 is an eight-channel 24-bit digital-to-analog converter (DAC) designed for digital audio systems. It uses AKM's advanced multi-bit architecture for its modulator, delivering a wide dynamic range while preserving linearity for improved THD+N performance. The AK4358 has full differential SCF outputs, removing the need for AC coupling capacitors and increasing performance for systems with excessive clock jitter. The AK4358 accepts 192kHz PCM data and 1-bit DSD data, making it ideal for a wide range of applications including DVD-Audio and SACD.
The AK4112B is a digital audio receiver (DIR) from Asahi Kasei that is compatible with 96kHz, 24 bits. It supports consumer and professional mode channel status decoding. The AK4112B can automatically detect a non-PCM bit stream. When combined with an AK4527B multi-channel codec, the two chips provide a system solution for AC-3 applications. The dedicated pins or a serial µP I/F can control the mode setting. The small package, 28-pin VSOP or 28-pin QFN, saves board space.
