Application

The The TDA7502 IC will interface with an external CODEC chip (i.e. the TDA7531). The CODEC chip contains A/D converters that convert the audio data and send it to the TDA7502 IC for signal processing. The TDA7502 then sends the processed audio data back to the CODEC for D/A conversion. A block diagram of the system is shown in Fig. 1 below.

Description

This TDA7502 is a high-performance, fully programmable DSP, suitable for a wide range of applications and particularly for Audio and Sound Processing. It contains a 24-bit 50 MIPS DSP core, several interfaces for control and data, plus a configurable PLL.

The computational power and the memory configuration make this device particularly suitable for in car equalisation. This device will offer the best trade-off between performance and cost when coupled with the TDA7531, or other devices of the same family. A library of sound processing functions of the TDA7502 is available for this device; some of these functions are: parametric equaliser, cross over filters, acoustic delay, dynamic compression, Vol/Bass/Treble/Fader, active equalisation, Stereo Spatial Enhancement.
