AUDIO PROCESSOR with SRS

■ GENERAL DESCRIPTION

■ PACKAGE OUTLINE

The NJW1140 is a sound processor includes all of the

functions required to process the audio signal for TV, such

as tone control, balance, volume, mute, and AGC functions.

Also the NJW1140 performs SRS 3D Stereo which

regenerates 3D surround sound with only two speakers.

All of the internal status and variables are controlled by

I²C BUS interface.

■ FEATURES

■ Operating Voltage

8 to 13V

■ I²C BUS Interface

NJW1140GK1

■ Internal 6 Input Audio Selectors and Monitor Output

■ The AGC circuit reduces volume difference among input sources.

■ Variable AGC Compression Level via I²C (4-levels)

■ Includes Dual Surround (SRS 3D Stereo and Simulated Stereo)

■ Variable Surround Effect Level via I²C(SRS mode, 2-Levels)

■ Low Noise VCA

■ Bi-CMOS Technology
