NTE1616 Integrated Circuit TV Sound IF Amp/Detector, Driver Description: The NTE1616 is a TV sound integrated circuit in a 14–Lead DIP type package that can be operated with no adjustment, using ceramic filters externally. This device contains a DC controlled attenuator, which has wide effective area and gentle characteristic in the changing, so it is convenient especially for a remote controlled set. Features: D Gentle Changing DC Controlled Attenuator is Convenient for Remote Controlled Sets. D Operation with Ceramic Filters makes TV Sound Circuit No Adjustment Completely D SRPP Output Circuit can be Driven Directly D Muting Works Quickly D Low Distortion Demodulation Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Power Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to 15V Voltage (Pin13, Pin14), V13, V14 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to 15V Output Current (Pin2), I2 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to 20mA Power Dissipation (TA = 75°C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 350mW Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –20° to +75°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –40° to +125°C Electrical Characteristics: (VCC = 12V, TA = +25°C ±3°C f = 4.5mHz, ∆f = ±25kHz, fM = 400Hz, AM MOD = 30% unless otherwise specified) Parameter Symbol Test Conditions Min Typ Max Unit VCC = 12V Zero Carrier 15 20 25 mA – 200 400 µVrms 450 600 750 mVrms – 0.4 1.0 % Vi ≥ 3mVrms –44 –55 – dB Total Supply Current ICC IF Limiting Voltage Vi(lim) –3dB point Detector Output Voltage VO AF Vi = 10mVrms Detector Output Distortion AM Rejection THDDET Vi = 10mVrms AMR DC VR Maximum Attenutation ATTVR fin = 400Hz, Vi = 600mVrms 70 80 – dB DC VR Distortion THDVR fin = 400Hz, Vi = 600mVrms V8 – 0.4 1.0 % Electrical Characteristics (Cont’d): (VCC = 12V, TA = +25°C ±3°C f = 4.5mHz, ∆f = ±25kHz, fM = 400Hz, AM MOD = 30% unless otherwise specified) Parameter AF Voltage Gain Symbol Test Conditions Min Typ Max Unit GVAF fin = 400Hz, Vi = 100mVrms, R3 = 1kΩ 11.5 15.0 – dB IF Input Resistance Rin – 1.5 – kΩ IF Input Capacitance Cin – 2.0 – pF Pin4 Input Resistance Rin4 – 20 – kΩ Pin4 Input Capacitance Cin4 – 2.9 – pF Pin Connection Diagram VCC 1 14 (+) IF Amp Input AF Output 2 13 (–) IF Amp Input Feedback 3 12 Low Pass Capacitor Attenuator Input 4 11 Regulated Voltage Detector Output 5 10 Discriminator Muting 6 9 Discriminator GND 7 8 DC Attenuator 14 8 1 7 .785 (19.95) Max .300 (7.62) .200 (5.08) Max .100 (2.45) .600 (15.24) .099 (2.5) Min
