NTE1576 Integrated Circuit Dual Volume Control/Balance/Tone Description: The NTE1576 is a DC controlled dual volume, balance and tone (Bass, treble) integrated circuit in 1 16–Lead DIP type package. As these dual channels are constructed on one chip, this IC is excellent in pair characterisitics and it is suitable for automobile stereo, radio cassette, music center, TV multiplex sound receiver and remote controlled applications. Features: D Wide Power Supply Voltage Range: Single Supply VCC (opr) = 8V to 14V Dual Supply VCC – VEE (opr) = ±4V to ±7V D Wide Volume Control Range: VR = 80dB (Typ.) D Excellent Cross Talk: CT = 70dB (Typ) D Stable for Temperature Drift D Wide Tone Control Range: VB = 10dB (Typ) at f = 1kHz 100Hz VT = 12dB (Typ) at f = 1kHz 20kHz Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14V Power Dissipation, PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 750mW Derated above 25°C . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6mW/°C Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –20° to +75°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –55° to +150°C Electrical Characteristic: (TA = +25°C unless otherwise specified) Parameter Quiescent Current Maximum Input Voltage Maximum Output Voltage Voltage Gain Symbol ICCQ VIN VOUT GV Test Conditions Min Typ Max Unit – 11 17 mA 10 18 25 mA BASS/TRBL/BAL SW1 – 3: B, VOL SW4: A, THD = 1% – – 1 Vrms 1 – – Vrms BASS/TRBL/BAL SW1 – 3: B VIN = 0.1Vrms, VOL SW4: A –0.5 2.0 4.5 dB VOL/BAL/BASS SW1 – 4: B VCC, VEE = ±4V Electrical Characteristic (Cont’d): (TA = +25°C unless otherwise specified) Parameter Symbol Channel Balance CB Test Conditions BASS/TRBL/BAL SW1 – 3: B VIN = 0.1Vrms, VOL SW4: A VOL/BAL/BASS/TRBL SW1 – 4: B, VIN = 0.1Vrms, f = 100Hz to 20kHz Volume Control Range VR Bass Control Range BASS/TRBL/BAL SW1 – 3: B, VOL SW4: A → C, VIN = 1Vrms Min Typ Max Unit –3 0 +3 dB –3.5 0 +3.5 dB 70 80 – dB 14 dB –7.0 dB VB Max VOL/BAL SW3,4: B, BASS/TRBL SW1,2: A 7 11 VIN = 1Vrms, VB Min f = 1kHz → 100Hz BASS/TRBL SW1,2: C –15.0 –11.5 Treble Control Range VT Max VOL/BAL SW3,4: B, BASS/TRBL SW1,2: A VIN = 1Vrms, VT Min f = 1kHz → 20kHz BASS/TRBL SW1,2: C 7 11 14 dB –20 –14 –10 dB Tone Error DGV VOL/BAL SW3,4: B, VIN = 1Vrms, BASS/TRBL SW1,2: C → A – 6 10 dB Total Harmonic Distortion THD BASS/TRBL/BAL SW1 – 3: B, VOL SW4: A, VO = 150mVrms – 0.1 0.35 % Output Noise Voltage VNO BASS/TRBL/BAL SW1 – 3: B, VOL SW4: A, BPF = 50Hz to 20kHz, Input Open – 130 300 µVrms Crosstalk CT BASS/TRBL/BAL SW1 – 3: B, VOL SW4: A, VOUT = 1Vrms – 70 – dB Control Terminal Input Resistance RIN Pin8, Pin9, Pin10 – 500 – kΩ Pin7 – 200 – kΩ Pin Connection Diagram VEE 1 Ch 1 Input 2 16 Reference Signal 15 Ch 2 Input Treble Freq Set 1 3 14 Treble Freq Set 2 Bass Freq Set 1 4 13 Bass Freq Set 2 Reference Control 5 Ch 1 Output 6 12 VCC 11 Ch 2 Output Balance Control 7 10 Treble Control Volume Control 8 9 Bass Control 16 9 .260 (6.6) Max 1 8 .785 (19.9) Max .300 (7.62) .200 (5.08) Max .245 (6.22) Min .100 (2.54) .700 (17.7)
