| 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 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20V Total Power Dissipation, PTOT . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1200mW Operating Ambient Temperature Range, TA . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -30 to +80C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -65 to +150C DC Electrical Charactertistics: (VCC = 12V, TA = +25C, RG 600, RL 4.7k, CL 200pF unless otherwise specified) Parameter Supply (Pin3) Supply Voltage (VCC) Supply Current (IC) V3-18 I3 VCC = 8.5V VCC = 12V VCC = 15V DC Input Levels (Pin4 and Pin15) V4, 15-18 VCC = 8.5V VCC = 12V VCC = 15V DC Output Levels (Pin8 and Pin11) under all control voltage conditions with DC feedback Pin17 Application with Internal Potentiometer Contour ON/OFF Switch (Control by I17) Application without Internal Potentiometer V17-18 -I17 V17-18 VCC = 8.5V Contour (Switch Open) Linear (Switch Open) VCC 10.8V, voltage range forced to Pin17(Contour cannot be switched OFF) 3.5 - 1.5 4.5 3.75 - - - 4.0 0.5 10 VCC/2-VBE V mA mA V V8, 11-18 VCC = 8.5V VCC = 12V VCC = 15V 7.5 19 25 30 3.8 5.3 6.5 3.3 4.6 5.7 - 27 35 43 4.25 5.9 7.3 4.25 6.0 7.5 16.5 36 45 56 4.7 6.6 8.2 5.2 7.4 9.3 V mA mA mA V V V V V V Symbol Test Conditions Min Typ Max Unit DC Control Voltage Range for volume, V1, 9, 10, 16 V17-18 = 5V bass, treble, and balance (Pin1, Using internal supply Pin9, Pin10, and Pin16 respectively) Input Current of Control Inputs (Pin1, -I1, 9, 10, 16 Pin9, Pin10, and Pin16) 1.0 0.25 - - - - 4.25 3.8 5 V V A AC Electrical Charactertistics: (VCC = V3-18 = 12V, TA = +25C, contour switch closed (linear posi tion), volume, balance, bass, and treble controls in mid-position, RG 600, RL 4.7k, CL 200pF, f = 1kHz unless otherwise specified) Parameter Control Range Maximum Gain of Volume Volume Control Range Balance Control Range Bass Control Range at 40Hz Treble Control Range at 16kHz Signal Inputs, Outputs Input Resistance (Pin4 and Pin15) R14,15 RO8,11 AV = 20dB, Note 1 AV = -40dB, Note 1 Output Resistance (Pin8 and Pin11) 10 - - - 160 - - - 300 k k AVmax AV AV AV AV AVmax/AVmin AV = 0dB 20.5 90 - 12 12 21.5 100 -40 15 15 23 - - - - dB dB dB dB dB Symbol Test Conditions Min Typ Max Unit Note 1.
