Integrated Circuit
dbx TV Noise Reduction Integrated Circuit
Description:
The NTE1859 is an integrated circuit designed for the dbx–TV noise reduction decode circuit for multi-
channel TV sound systems. This device contains a voltage controlled amplifier, a variable de–empha-
sis circuit with new configuration and RMS detectors with completely integrated active band pass fil-
ters, and offers the complete dbx–TV noise reduction decoder only with a few external components.
Features:
Integrated Band Pass Filters using Active Filtering Technique and Thin Film Structure with
High Capacitance
Variable De–emphasis Circuit with New Circuit Configuration
Minimum Number of External Components
Wide Operation Voltage Range: 4.7V to 16V
