AKM’s New DAC family delivers a Huge Power Saving, Multi-Channel Solution for Consumer and Car AV Systems

Tokyo, Japan —Asahi Kasei Microsystems Co., Ltd. (AKM), a leading supplier of audio ICs for professional and consumer markets, today launches the AK4346 and AK4348, low power 6 and 8-channel, 24-bit Audio DACs. This new family of chips has been especially developed to achieve power savings in consumer and car audio systems and is part of AKM’s Audio4homeTM range.

The AK4346 and AK4348 are compatible with the existing 192 kHz, 8-channel AK4359 DAC. However, the new DACs operate with a lower 3.3 voltage power supply and the power dissipation is reduced by 46 per cent when compared with the AK4359. The new family has a 104dB dynamic rang and delivers a very high quality sound. The AK4346 with 6-channels and AK4348 with 8-channels, offer the versatility needed to support wide-ranging applications including DVD/DVD-Audio, AV amplifiers, and car audio systems.

The new DACs make full use of AKM's advanced multi-bit delta-sigma modulator and the low jitter performance of AKM's switched-capacitor (SC) technology. A digital FIR filter with linear phase, delivers high quality undistorted sound. Both chips have built-in de-emphasis filters, soft mute, zero detection functions, channel independent digital ATT, and a TDM audio interface for a simplified DSP interface. The microcomputer interface is compliant with both three-wire and I2C interfaces.

The AK4346 and AK4348 are available in 30-pin VSOP package. Evaluation boards and samples are available now. To obtain more information, contact AKM, Audio & Video Business Operation, Nishi-Shinjuku 1-23-7, Shinjuku-ku, Tokyo 160-0023, Japan.
