NJW1167/A
AUDIO PROCESSOR with Subwoofer Output
www.datasheet4u.com
s GENERAL DESCRIPTION
The NJW1167/A is a sound processor with subwoofer
output includes all of functions processing audio signal for
TV, such as tone control, balance, volume, mute, and AGC
functions.
Also the NJW1167/A includes the LPF for subwoofer
output and bass boost function.
The original surround system reproduces natural surround
sound and clear vocal orientation.
All of internal status and variables are controlled by I2C
BUS interface.
