.Data Sheet.co.kr ASAHI KASEI [AK4352] 2V & Low Power Multi-Bit ∆Σ DAC AK4352 GENERAL DESCRIPTION The AK4352 is an 18bit low voltage & power stereo DAC for digital audio system. The AK4352 uses the new developed Multi-Bit ∆Σ architecture, this new architecture achieves DR=94d B at low voltage operation. The AK4352 includes post filter with single-ended output and does not need any external parts. The AK4352 is suitable for the portable audio system like MD, etc as low power and small package.
