Technical content

Video IF IC for TBA 1440 G Black/White and Colour TV Sets TBA 1441 The types TBA 1440 G (for pnp tuner prestages) and TBA 1441 (for npn tuner prestages) have been developed from TBA 440 P/N. Their decisive improvements are ‘@ Reduced residual IF at outputs 11 and 12 @ Reduced residual IF at pin 13 @Considerably improved intermodulation distance @ Excellent tuning attitude even with low-ohmic tank circuit at demodulator The IC’s contain a high — amplifying controllable video IF amplifier, a controlled demodulator and two low-resistance video outputs with positive- and negative-going signals as well as the complete keyed control and delayed tuner control. @Large control range with low noise and wide dynamic range @ High sensitivity @ Controlled demodulator, so minimum 1.07 MHz disturbances @ Internal temperature stabilization @ The white levels of the video signals at the positive and negative video output are in- dependent of the operating voltage. @ The whites and black levels can be adjusted separately Package outlines TBA 1440 G, TBA 1441 7602-4 2 | Type Ordering codes : Ist S TBA 1440 G | 067000-A1022 Use | (re | TBA 1441 067000-A1224 art ab5le =| Mom | LPO ibttar Leap. 6 9 pon P| Pres plugin package 20.A 16 DIN 41866 16 pins, dual-in-iine i 5 Weight approx. 1.2.9 agp ——4t Dimensions in min Absolute maximum ratings Supply voltage Ysa 15') v Voltages Vs 5 v Vs, 20 v Vie 5 v Ohmic resistance between pins 8 and 9 Res =20 Q Thermal resistance (system-air) Rivea 100 K/w Junction temperature T, 150 °C Storage temperature iA 40 to +125 | °C Range of operation Supply voltage Via 10.5 to 15 v Ambient temperature in operation Tame -25 to +60 | °C *) briefly 16.5V_
