DESCRIPTION

The TDA7300 is a volume, tone (bass and treble),

balance (left/right) and fader (front/rear) proces-

sor for high quality audio applications in car radio

and Hi-Fi systems.

Control is accomplished by serial bus microproc-

essor interface.

The AC signal setting is obtained by resistor net-

works and analog switches combined with opera-

tional amplifiers.

The results are: low noise, low distortion and high

dynamic range.

This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
