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 complete multiplexed sound system for US NTSC System television sets can be built by interfacing the NTE1801 with the NTE1800 Multiplexed Sound Decoder.

Features:

• Low Distortion Ratio, Low Interference

• Low Power Supply Current

• Single, 8V to 15V Power Supply

• 100mVrms (300Hz, 0dB) Input Voltage (Pin4)

• Easily Interfaced to the NTE1800

Functions:

• On–Chip dbx Noise Reduction Decoder and VCA Circuits

• On–Chip RMS Level Sensor

• L + R Signal Buffer Amplifier
