Offered as a low-cost solution for multi-channel audio systems, the AK4355 d/a converter is capable of 192 kHz DVD-audio sampling. This six-channel, 24-bit d/a converter features a built-in digital volume control for adjusting channel balance, satisfying Dolby digital standards. Other features include a dynamic range of 106 dB, 24-bit 8x digital filter with switchable slow roll-off, THD+N of -90 dB, channel-independent digital attenuator, and a three-wire control interface. Similar to its predecessor, the AK4356, the device incorporates a multi-bit architecture, said to provide anti-jitter performance that matches that of switched-capacitor d/a converters. Available in a 28-pin VSOP, price is $4.15 each/1,000.
