The TDA offers provisions for the feeding of an amplitude indicator, either positive or negative going mono-stereo voltage, AFT output push-pull-current output with automatic switch-off, squelch adjustable for more than 40 dB range of input signal and depending on detuning. For single amplifier performance, see TAA data sheet.

The selection can be carried out by merely touching the sensor plates. At the same time, a previously selected stage is reset via the coupling resistance R c which is common to all stages.

By means of its amplitude-controlled oscillator, the TDA is particularly suited for applications with varicap diodes. Plastic plug-in package Plastic packages are soldered on the side of dztasheet printed circuit board opposite to the case, the pins are vertically bent and fit into holes at an equal distance of 7. Applications of this kind can be used for level sensors, VU-meters, tachometers, field strength indicators etc. Receiving quality The figures shown in the table are warranty-figures.

Solitary circuits The first letter identifies the circuit as: Applications of this kind can be used for level sensors, VU-meters, tachometers, radio scales etc.

S is particu- larly suited fzh11 sets where a low current consumption is of importance, or where major supply voltage fluctuations occur.

Thereby the otherwise feared tendency of oscillating at low frequencies of the range of medium waves is disappearing.

Daehan Building, 8th floor, 75, Susomun-dong, Chung-ku C. The window discriminator analyses the height of the input voltage between two externally adjustable limits. The application The described Integrated Circuits can be used in all cases where a channel selection 1-outof-n shall be carried out. With the switch St-Such stereo transmitters can be selected. Test conditions min typ max K 1. Terms of delivery and rights to change design reserved.

As can be seen, the temperature drift is inferior. With adequate external circuitry several IC’s can be connected in series.

TDA contains a controlled RF pre and intermediate stage, a multi- plicative push-pull mixer with separate oscillator, controlled IF amplifier, full-wave de- modulator, active low pass, as well as an amplifier to directly feed a field-strength indicator instrument. The leads should be clipped before soldering. When using rapidly rising motors, the preload circuitry reduces an overrun. Also, each channel follows an identical lay-out to ensure equal frequenc behaviour of the three channels.


For the indication, it can be chosen between neon lamps, nixie tubes, LED’s or filamental lamps. The display range is determined by the resistors R 3R 4and R 5. TBB B 8 pins in plastic plug-in package. L 1Avenue Tombalbaye B.

Figure 6 shows an application circuit forfilamental lamps or LED’s as indicating elements. Thus the case need not be held down while soldering. Tq i Tq Circuit: Switch St switches the tuning voltage preselected with the potentiometer to the tuning output pin 1 1, switch S 2 sends a signal to the output for chan- nel indication and band selection. If adequate heat sinking is provided, they can deliver over 1 A output current. In analogy to the input voltage, the discrete LED’s are forming at the output a light spot.

SAS S only: The resistance R p corresponds to the potentiometer resistance. Symbols and terms used The logic symbol “operational amplifier” shows only signal inputs and outputs. The leads are connected to the printed circuit by iron soldering or spot welding. Figure 4 shows an extension of the circuit to 24 diodes with 2 UAA
