NTE15023 Integrated Circuit
dbx TV Noise Reduction Integrated Circuit
Description: The NTE15023 is an integrated circuit designed for the dbxTV noise reduction decode circuit for multichannel TV sound systems. This device contains a voltage controlled amplifier, a variable deemphasis circuit with new configuration and RMS detectors with completely integrated active band pass filters, and offers the complete dbxTV 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 Deemphasis 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 Allowable Power Dissipation, PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 715mW Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20° to +75°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 55° to +150°C Recommended Operating Voltage: Power Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5V to 15V Electrical Characteristics: (TA = +25°C, VCC = +9V Reference Level: 0dB = 5dBm (436mVrms) unless otherwise specified)
