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
