BW0405XA
GENERAL DESCRIPTION
This product is SD Digital-To-Analog Converter for digital audio System (CDP). The product 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 90dB SNR (Signal to Noise Ratio) over in band (20kHz).
The product 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.
