TDA7311
SERIAL BUS CONTROLLED AUDIO PROCESSOR
TDA7311
Input Multiplexer - Two Stereo Differential Inputs - Two Stereo Single Ended Inputs - One Mono
Differential Input And Output For External Equalizer Or Noise Reduction System Volume Control In
1.25db Steps Treble And Bass Control Four Speaker Attenuators: - 4 Independent Speakers Control
In 1.25db Steps For Balance And Fader Facilities - Independent Mute Function All Functions
PROGRAMMABLE VIA SPI COMPATIBLE SERIAL BUS
Description
The Tda7311 Is A Volume, Tone (bass And Treble) And Fader (front/rear) Processor For High Quality
audio
Applications in car radio and Hi-Fi systems.
ORDERING NUMBER: TDA7311
Control Is Accomplished By Serial Bus Microprocessor Interface. The Ac Signal Setting Is Obtained By
Resistor Networks And Switches Combined With Operational Amplifiers. Thanks To The Used Bipolar/cmos
technology, low distortion, low noise and DC stepping are obtained.
