Dolby∗ B-C Type Noise Reduction System for Playback
The CXA2502M is a bipolar IC incorporating stereo
Dolby B-C type noise reduction (NR) system for
Pins of this IC are compatible with those of the
Dolby B type NR ICs CXA1102M/ CXA1552M.
A reduction in the number of external parts and
small package have been achieved due to the fact
that the spectral skewing circuits are all on-chip and
this IC is intended for playback.
• Few external parts
• Spectral skewing circuit are on-chip
• NR OFF/B/C and AUX/TAPE switches
