7403
DESCRIPTION
The TDA7403 is a high performance signal processor specifically designed for car radio applications focused on the low-end market. The device includes a plete audioprocessor and a stereo decoder with noiseblanker. Switched-capacitors design technique allows to obtain all these features without external ponents or adjustments. Using TDA7403 results is in a very performant low-cost signal processing BLOCK DIAGRAM
ORDERING NUMBER: TDA7403D application The device is fully programmable by I2C bus interface allowing to customize key device parameters and especially filter characteristics. The BICMOS process bined with the optimized signal processing assure low noise and low distortion performances.
