TDA4565

The TDA4565 is a kind of picture improvement circuit for color TV.

There are some features of TDA4565 as follows: (1)integrated, matchable gyrator chain, adjustable in steps of 45 ns from 730 to 1045 ns; (2)steepens the slope of the color difference signals (R-Y) and (B-Y), suitable for pos, and neg. color difference signals; (3)Y-output with less delay for applications with future features (i.e., modulation of horizontal deflection).

What comes next is about the absolute maximum ratings about TDA4565 (reference point pin 18, unless otherwise specified): (1)supply voltage at pin 10, VS: 13.2 V; (2)voltage at pins 1, 2, 12 and 15: VS V; (3)voltage, V7-V6: 5 V; (4)voltage, V8-V9: 5 V; (5)voltage at pin 11, V11: VS-3 V; (6)voltage at pin 17, V17: 0 to 7 V; (7)current at pin 6, I6: ±10 mA; (8)current at pin 9, I9: ±10 mA; (9)maximum power dissipation, Ptot: 1.1 W; (10)ambient temperature range, Tamb: 0 to +70; (11)storage temperature range, Tstg: -25 to +125.
