CXA2502M
Dolby∗ B-C Type Noise Reduction System for Playback
Description
The CXA2502M is a bipolar IC incorporating stereo
Dolby B-C type noise reduction (NR) system for
playback.
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.
Features
• Few external parts
• Spectral skewing circuit are on-chip
• NR OFF/B/C and AUX/TAPE switches
• Small package (16-pin SOP)
• Low current consumption 12mA Typ.
• Built-in two channels
Structure
Bipolar silicon monolithic IC
Absolute Maximum Ratings (Ta = 25°C)
• Supply voltage
VCC 17 V
• Operating temperature Topr –40 to +85 °C
• Storage temperature Tstg –65 to +150 °C
• Allowable power dissipation
PD 600 (SOP) mW
16 pin SOP (Plastic)
