TQFP44 ORDERING NUMBER: TDA7411
DESCRIPTION The TDA7411 is the successor of the TDA7407 in the CSP family introduced by the TDA7460/61.
It uses the same innovative concepts and design technologies allowing fully software programmability through I2C bus and overall cost optimization for the system designer.
The device includes a three band audio processor with extended configurable input and output stagBLOCK DIAGRAM es and absence of external components for filter settings, a last generation stereo decoder with multi path detector and a sophisticated stereo blend, high cut control and noise cancellation circuitry.
Strength points of the CSP approach are flexibility and overall cost/room saving in the application, combined with high performances.
