Description

The CXA1917AM/AS is a bipolar IC designed for

use in the Dolby S type noise reduction system (NR).

An external operational amplifier is required to

configure the decoder. The stereo Dolby B-C-S type

NR combines use of a CXA1563M/S and two

CXA1917AM/AS ICs.

Features

• Considerable reduction in the number of external parts

(half compared to CXA1417S/Q)

• The same Dolby level as that of CXA1560 series ICs (–6dBm)
