| NTE746 Integrated Circuit TV Video IF Amplifier Description: The NTE746 is a monolithic integrated circuit in an 8-Lead DIP type package with wide-range AGC for replacement of 1st and 2nd IF stages in solid-state color and black and white TV sets. It will directly drive a 3rd IF stage. Features: D Center Frequency: FO = 45MHz D Bandwidth: BW = 6MHz D Power Gain: 50dB Min D AGC Range: 60dB Min D Low Reverse-Transfer Admittance: 1mho Typ D D D D Y21 Constant to 75MHz 12V Operation, Single-Polarity Power Supply Total Supply Current: 20mA Typ Nearly Constant Input and Output Admittance over the Entire AGC Range Applications: D TV Video IF D Defense Communications Satellite Programs D Combined AM/FM Radio IF Amplifiers D Linear Switch or Chopper for Multiplex Modulation or Demodulation Absolute Maximum Ratings: (TA = +25C) Power Supply, V+ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Output Supply, V1, V8 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V AGC Supply, VAGC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4V < VAGC < V+ Differential Input Voltage, Vin . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7V Power Dissipation, PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 625mW Derate Above 25C . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5mW/C Operating Temperature Range, TA . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to +75C Electrical Characteristics: (V+ = 12V, TA = +25C unless otherwise specified) Parameter DC Characteristics Total Supply Current Output Stage Current AGC Supply Voltage AGC Supply Current IS I1 + I8 VAGC IAGC 0dB Attenuation 60dB Attenuation 0db Attenuation 60dB Attenuation Pin1, Pin2, and Pin8 - - - - - - 20 6.5 5.0 6.9 0.1 0.2 - - - - - - mA mA V V mA mA Symbol Test Conditions Min Typ Max Unit Electrical Characteristics (Cont'd): (V+ = 12V, TA = +25C unless otherwise specified) Parameter Power Gain Y-Parameters Single-Ended Input Admittance Differential Output Admittance Differential Admittance Variation w/ AGC Input Admittance Output Admittance g11 b11 g22 b22 g11 b11 g22 b22 Y21 Useable AGC Range in 45MHz TV IF Pin Connection Diagram Symbol Test Conditions BW = 6MHz Min - - - - - Typ 46 1.0 2.8 0.07 0.50 0.06 0.0 0.004 0.04 0.2 > 60 Max 50 - - - - - - - - - - Unit dB mmho mmho mmho mmho mmho mmho mmho mmho mho dB Small-Signal Characteristics (f = 45MHz) 0dB to 60dB - - - - 0dB Agc - - IF Output 1 VCC 2 8 7 6 5 IF Output GND (+) Input Input GND 3 (-) Input 4 8 5 .260 (6.6) 1 4 .390 (9.9) Max .155 (3.93) .300 (7.62) .100 (2.54) .300 (7.62) .145 (3.68) |
