STMicroelectronics TDA7464
The TDA7464 is a volume tone (bass middle and D96AU483C treble) balance (Left/Right) processors with stereo SRS and voice canceller for quality audio applica- tions in car radio, Hi-Fi, TV systems. It reproduces SRS (Sound Retrieval System) sound by external components and surround specification. The AC signal setting is obtained by resistor Thanks to the used BIPOLAR/CMOS Technology, networks and switches combined with operational Low Distortion, Low Noise and DC stepping are amplifiers according to the SRS laboratories obtained.| Part No. | TDA7464 |
