NTE1803
NTE1803 is Integrated Circuit Stereo Audio Controller manufactured by NTE Electronics.
Description
: The NTE1803 is an linear integrated circuit in a 18- Lead DIP type package designed as an active stereo tone/volume control for car radios, TV receivers, and audio equipment. It includes functions for bass and treble control, volume control with built- in contour (can be switched off), and balance. All these functions can be controlled by DC voltages or by single linear potentiometers. The bass and treble responses are defined by a single capacitor per control per channel. Features
: D Few External ponents Necessary D Low Noise due to Internal Gain D Bass Emphasis can be Increased by a Double- Pole Low- Pass Filter D Wide Power Supply Range Applications: D Hi- Fi Radio D Auto Radio D TV D Audio Systems Absolute Maximum Ratings: Supply Voltage (V3- 18), VCC
