GENERAL DESCRIPTION The TDA2595 is a monolithic integrated circuit intended for use in colour television receivers. Features · Positive video input; capacitively coupled (source impedance < 200 ) · Adaptive sync separator; slicing level at 50% of sync amplitude · Internal vertical pulse separator with double slope integrator
TDA2595
· Output stage for vertical sync pulse or composite sync depending on the load; both are switched off at muting · 1 phase control between horizontal sync and oscillator · Coincidence detector 3 for automatic time-constant switching; overruled by the VCR switch · Time-constant switch between two external time-constants or loop-gain; both controlled by the coincidence detector 3 · 1 gating pulse controlled by coincidence detector 3 · Mute circuit depending on TV transmitter identification · 2 phase control between line flyback and oscillator; the slicing levels for 2 control and horizontal blanking can be set separately · Burst keying and horizontal blanking pulse generation, in combination with clamping of the vertical blanking pulse (three-level sandcastle) · Horizontal drive output with constant duty cycle inhibited by the protection circuit or the supply voltage sensor · Detector for too low supply voltage · Protection circuit for switching off the horizontal drive output continuously if the input voltage is below 4 V or higher than 8 V · Line flyback control causing the horizontal blanking level at the sandcastle output continuously in case of a missing flyback pulse · Spot-suppressor controlled by the line flyback control QUICK REFERENCE DATA Supply voltage (pin 15) Sync pulse amplitude (positive video) Horizontal output current PACKAGE OUTLINE 18-lead DIL; plastic (SOT102); SOT102-1; 1997 January 07.

SOLDERING Introduction
TDA2595
There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. Repairing soldered joints Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 °C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 °C, contact may be up to 5 seconds. DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. 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. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification.
