AL0402I is Digital-To-Analog Converter for digital audio System (CDP). AL0402I contains Serial-to-Parallel Converter and Compensation Filter, Digital Volume Attenuator by the MICOM Interface, De-Emphasis Filter, FIR filter, Sinc Filter,digital sigma-delta modulator, analog postfilter, AIF (Anti-Image-Filter). The normal input and output channels provides 95dB SNR (Signal to Noise Ratio) over in band (20kHz).
AL0402I employs the 1bit 4th-order sigma-delta architecture with 16bit resolution, over sampling of 64X. And analog postfilter with low clock sensitivity and linear phase, filters the shaping-nosie and outputs analog voltage with high resolution. An on-chip reference voltage is included to allow single supply operations.
