Features
TDA7415CB
The TDA7415CB is composed of four major building blocks. - The IN-section, the spectrum-
analyzer, the main signal processing path and the OUT-section; Individually featuring:
IN-section
● Three independent signal-paths (front, rear and auxiliary) with independent soft-mute.
● Six stereo inputs; 3 single ended; 1 single ended or full differential mono; 2 quasi-
differential.
● ±15dB level-adjust with 1dB steps.
● Pin-accessible and/or I²C/SPI-controlled soft-mute (direct mute) for each signal path.
Spectrum-analyzer
● 7-band, fully integrated 2^nd-order band-pass filters with programmable filter quality for
different visual behavior.
● Dedicated one or two-wire serial port for analog data-readout.
● Analog output voltage 3,3V-μP compatible.
Main signal processing path
● ±15dB level-adjust with 1dB steps.
● Fully integrated bass-, middle- and treble-tone control. All filters offer 2^nd-order
frequency response with programmable filter quality and center frequency.
● Room-acoustics notch filter (Room-EQ) allows the suppression of primary car-body
resonance.
OUT-section
● Three independent signal-paths (front, rear and others) with individual soft-mute.
● Four AC-coupled, single ended stereo inputs.
● Pin-accessible soft-mute (direct mute), for each signal path.
● I²C/SPI-controlled soft-mute, independent for all six (mono) channels
● Main signal path monitor-select (pre/post tone control).
● L/R-channel independent phone, navigation or phone/navigation-mix signal interrupts
for front signal path; L/R-channel independent phone or navigation interrupts for rear-
and others-path.
● 2^nd-order frequency response high-pass filters for front- and rear-signal path.
● 2^nd-order frequency response subwoofer low-pass filter for others-signal path.
● Soft-step volume with 79 to 25dB range for each signal path.
● Four dedicated outputs for an internal (on-board) power amplifier.
● Six 4V_RMS line-driver outputs for an external (remote) power amplifier.
● Offset voltage detection circuit for on-board power amplifier failure diagnosis.
