1 / 3 page NTE15023 Integrated Circuit dbx TV Noise Reduction Integrated Circuit Description: The NTE15023 is an integrated circuit designed for the dbx–TV noise reduction decode circuit for mul- tichannel TV sound systems. This device contains a voltage controlled amplifier, a variable de–em- phasis circuit with new configuration and RMS detectors with completely integrated active band pass filters, and offers the complete dbx–TV noise reduction decoder only with a few external components. Features: D Integrated Band Pass Filters using Active Filtering Technique and Thin Film Structure with High Capacitance D Variable De–emphasis Circuit with New Circuit Configuration D Minimum Number of External Components D Wide Operation Voltage Range: 4.7V to 16V Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Power Supply Voltage, VCC 17V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
