Connection in a matrix yields a cross-talk suppression which is typically higher than 8 dB. After inserting the package into the printed circuit board two or more pins should be bent at an angle of app.
Analogue circuit; temperature range: All definitions refer to symmetrical supply voltages. The current source CG serves as operating resistance for the fzn111 of all stages, even for those of further components. The actual value can only be measured at transition from D, to D 2. Thus, cross-talking can be improved.

Three letters followed by a serial number First two letters A. Thus the resistance relationship are: Input impedance Operation at They should be covered. Four output signals are available which have the following meanings: Voltage at pin 14 without colour sync signal with colour sync signal peak-to-peak value of 0.
Parameter is the volume. In addition they provide the very significant inherent integrated circuit advantages of close electrical and thermal matching.
Switching through of the tuning voltage The switching through of the tuning voltage was subject to particular care during develop- ment. BA T’ according to required current e. The RS flipflop is set by T 6.
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. Figure 5, therefore, shows, as example of a typical application, a circuit for the selection of 8 channels in a TV sets. AQL, critical electrical defects: The voltage difference between pins 16 and 3 corresponds thereby to the possible indication range. Thus the package need not be held down while soldering.
A stabilized voltage approx. Current limit transistor may be used for shutdown if current limiting is not required.

They have been developed in consideration of the particular requirements of radio and TV sets. Two outputs are available for each stage: Ring scales are obtained by a circular arrangement of the diodes. Electrical defects Single AQL, gradual electrical defects 1. UJ S1 open – S2 closed. They are outstanding by reason their large common- mode voltage range and short circuit protection.
The circuit is directly interchangeable with TBA A pin-compatible. The voltage divider is to be dimensioned according to the desired input voltage. The basic brightness is determined by the resistor R 7 approx.
The diodes D 16 or D 17 light permanently, when the reciprocal absolute ratings are exceeded. The input signals are suppressed at the outputs. The chip lay-out has been designed to ensure tight thermal coupling between all the transistors in each channel to minimize and equalize thermal drifts between channels.

It is practically independent of temperature and supply voltage. Pin connections Pin 1 Ground 2 Sensor input for AFT switch off 3 AFT switch off time constant 4 Low-pass capacitor for detuning-dependent AF switch off 5 AFT output push-pull output 6 Low-pass capacitor for suppression of switch off clicks in case of detuning and insufficient field strength 7 AF output emitter follower with constant-current source 8 Output of limiter amplifier.
When switching voltage applied the emitter follower, BCon the output is blocked and the buffer stage, BCis switched on. For single amplifier performance, see TAA data sheet. SAS is the basic component for the first 4 channels. The ratio of the chrominance signal to the colour sync signal is at nominal contrast 3 dB below maximum and at nominal saturation 6 dB below maximum the same at the output and at the input.
The symmetric composition of the circuit allows a high stability against oscillating and, at the same time, an AGC range of more than dB. Catastrophic failures broken or cracked packages, wrong type-marking, wrong position of the package-nose or marking of pin 1, pins not solderable.
