The Ak4373 is a low-power 24-bit stereo DAC that features advanced digital audio processing, stereo line outputs, stereo headphone deriver, and a mono speaker driver.
The headphone driver can be configured in several ways, including 45mW single-ended or pseudo-cap-less mode, or a 90mW differential mode. The advanced audio processing block incorporates DSP-like functions, including LPF&HPF, frequency Compensation, 3D-enhancement, ALC/Limiter and five uncommitted bi-quads. The device has an auxiliary analog input with mixers for output circuits that can be used for simple noise-cancellation. The AK4373 supports either IIC or 3-wire for microprocessor interface and is available in a small 32-pin QFN package to offer space saving.
