At the feedback input pin 9 a part of Idefl is fed back gda4866 the input stage. To achieve good noise suppression the following values for Rp are recommended: Maximum output currents I4 and I6 are limited by current protection.

The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified storage maximum. Output stages The two output stages are current driven in opposite phase and operate in combination with the deflection coil in a full bridge configuration.

Stress above one or more of the limiting values may cause permanent damage to the device. The deflection current through the coil Idefl is measured with the resistor Rm which produces a voltage drop Urm of: These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Deviation of the output slope at a constant input slope. Due to the bridge configuration of the two output stages DC-coupling of the deflection coil is achieved.

Due to the feedback loop gain VU loop and internal bondwire resistance Rbo correction factors are required to determine the accurate value of Idefl: Product specification This data sheet contains final product specifications. The differential input stage has a high CMRR differential current mode input pins 1 and 2 that results in a high electro-magnetic immunity and is especially suitable for driver units with differential e.

Publication thereof does not convey nor imply any license under patent- or other industrial or intellectual property rights. Plastic or metal protrusions of 0. Flyback generator During flyback the flyback generator supplies the output stage A with the flyback voltage. The differential input stage delivers the driver signals for the output stages. This circuit will be activated when flyback pulses are missing, which is the indication of any abnormal operation.

Application information Where application information is given, it is advisory and does not form part of the specification. The feedback input has a current input characteristic which holds the differential voltage between pin 9 and the output pin 4 on zero. Frequency behaviour of Goi and Gofb: Ten uklad to odchylanie V, a na n.

Preliminary specification This data sheet contains preliminary data; supplementary data may be published later. High bandwidth and excellent transition behaviour is achieved due to the transimpedance principle this circuit works with.

The TDA consists of a differential input stage, two output stages, a flyback generator, a protection circuit for the output stages and a guard circuit. No liability will be accepted by the publisher for any consequence of its use. This makes it possible to optimize power consumption supply voltage VP and flyback time flyback voltage VFB.

The deflection current can be adjusted up to? Any difference of this comparison leads to a more or less driver current for the output stages.

Therefore the TDA requires no external coupling capacitor e. Equivalent to discharging a pF capacitor through a 0 Ohm series resistor. Jezeli bedzie sie dalej palil to padl ci scalak.

Zalanczam aplikacje tego scalaka dla zapoznaia sie z nim. Ten rezystor jest bezpiecznikiem. Guard circuit Rm I 9?

TDA , Tube TDA; Röhre TDA ID, IC – Integra

Hotel Minsk Business Tdq4866, Bld. I idc I defl 4. The circuit provides a high CMRR current driven differential input. A layer of silicon grease between the mounting base and the heatsink optimizes thermal resistance. Voltages refer to pin 5 GND.

Due to the absence of a decoupling capacitor the flyback voltage is fully available. Protection The output stages are protected against: If the printed-circuit board has been pre-heated, forced cooling fda4866 be necessary immediately after soldering to keep the temperature within the permissible limit.

The relation between the deflection current and the differential input current Iid is: The guard signal is active HIGH: Calculated values VP 8. Philips Semiconductors Philippines Inc. Driver units with voltage outputs are simply applicable as well e. Therefore the feedback current I9 through Rref is: Reproduction in whole or in part is prohibited without the prior written consent of the copyright owner.

The internal guard circuit will not be activated, if the input signals on pins 1 and 2 delivered from the driver circuit are out of range or at short-circuit of the coil pins 4 and 6. The total contact time of successive solder waves must not exceed 5 s.
