Attenuator by
Filter,
modulator,
the MICOM Interface,
postfilter,
(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.
Applications
CD Player, Portable CD Player, CD-ROM, Video-CD,
Mini-Disk, DVD etc
