TDA7402
1.0 DESCRIPTION OF THE AUDIOPROCESSOR PART
1.1 Input stages
In the basic configuration two full-differential, two mono-differential, one single ended stereo and one single-
ended mono input are available. In addition a dedicated input for the stereodecoder MPX-signal is present.
Figure 1. Input-stages
Full-differential stereo Input 1 (FD1)
The FD1-input is implemented as a buffered full-differential stereo stage with 100k
input-impedance at each
input. The attenuation is programmable in 3 steps from 0 to -12dB in order to adapt the incoming signal level.
A 6dB attenuation is included in the differential stage, the additional 6dB are done by a following resistive divid-
er. This input is also configurable as two single-ended stereo inputs (see pin-out).
Full-differential stereo Input 2 (FD2)
The FD2-input has the same general structure as FD1, but with a programmable attenuation of 0 or 6dB em-
bedded in the differential stage.
