Overview
NTE1803 Integrated Circuit Stereo Audio Control 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 Components 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 .
