NTE1801 Datasheet | NTE Electronics

Description : The NTE1801 Multiplexed Sound dbx Noise Reduction Decoder is a single- chip linear IC in a 28- Lead DIP type package suitable for US NTSC System use. The device incorporates two RMS- level sensors and VCA circuits, as well as five operational amplifiers and two buffer circuits. A plete multiplexed sound system for US NTSC System television sets can be built by interfacing the NTE1801 with the NTE1800 Multiplexed Sound Decoder.
