TDA7415CB STMicroelectronics

TDA7415CB Car-radio multimedia signal processor (CMSP) Features 6-channel multimedia approach Fully integrated tone control with notch filter 7-band spectrum analyzer Inputs LQFP64 Three independent signal paths Eight single-ended inputs Two quasi-differential inputs Optional full-differential input Level adjust gain-stages Description Independent soft-mute and direct-mute The TDA7415CB is the first 6-channel multimedia approach in the car-radio signal processor (CSP) Outputs family. It features full software programmability of Three independent signal paths three independent sections. The signal processor combines a three band audio tone control with an Six output channels with soft-step volume additional notch filter, high/low pass filters for Output level up to 4VRMS subwoofer support and a spectrum-analyzer with Independent soft-mute and direct-mute the absence of any external components for the internal filters. Versatile input/output stages and an Flexible phone/navigation interrupts extended signal routing scheme provide all the High-pass and subwoofer low-pass filters flexibility that is needed to serve modern 6-channel applications such as required by DVD technology.
