AKM Ships Integrated SACD/DVD-Audio DACs

November 17, in SACD News

IC manufacturer AKM has brought the reality of widespread multi-standard SACD and DVD-Audio players one step closer with the introduction of a range of digital-to-analogue converters that are able to accept both unpacked 192kHz PCM from DVD-Audio and Direct Stream Digital, the SACD carrier.

AKM Semiconductor Inc. have made available the AK4383, a two-channel DAC and the AK4357, the world’s first 6-channel DSD IC. Both products utilize AKM’s advanced 32-level multi-bit delta-sigma modulator and feature the jitter tolerant performance of AKM’s switched-capacitor (SC) technology.

Features of both devices include direct balanced (differential) outputs which reduce implementation costs while increasing the performance for systems with excessive clock jitter, a digital volume control, and a “soft Mute” function. This feature allows for the changing of input streams without stopping the signal transmission. The product line has a simple 3-wire interface for connection to decoders, DSPs or microcontrollers, 106dB dynamic range (112dB on the AK4383) and operate from a single 5-volt supply.

Richard Kulavik, Marketing Manager of AKM Semiconductor, “AKM has long been the leader in single-chip, multi-channel digital-to-analog converters. Our DACs and analog ICs are found in many professional and consumer products currently available. The AK4357 and AK4383 will power the next-generation of products by providing both the quality and cost-performance that people have come to expect from AKM.

The AK4357 is available in a 48-pin LQFP package and is priced at $4.84 in quantities of 1,000. The 2-channel AK4383 is available in a 20-pin TSSOP package and is priced at $2.59 in quantities of 1,000.
