APLICATION SUGGESTIONS
The first and the last stages are volume control blocks. The control range is 0 to -47dB (mute) for the first
one, 0 to -79dB (mute) for the last one. Both of them have 1dB step resolution.
The very high resolution allows the implementation of systems free from any noisy acoustical effect. The
TDA7449L audioprocessor provides 2 bands tones control.
3.1 CREF
The suggested 10
F reference capacitor (CREF) value can be reduced to 4.7F if the application requires
faster power ON.
