TDA4882 General Description
The TDA4882 is an RGB pre-amplifier for colour monitor systems with SVGA performance, intended for DC or AC coupling of the colour signals to the cathodes of the CRT.
With special advantages the circuit can be used in conjunction with the TDA485x monitor deflection IC family.
TDA4882 Maximum Ratings
| SYMBOL | PARAMETER | MIN. | MAX. | UNIT |
| Vext | external DC voltage applied to the following pins: pin 7 (VP) pins 2, 5 and 8 (signal inputs) pins 20, 17 and 14 (current outputs) pins 12, 15 and 18 (channel feedback inputs) pins 1, 6, 3 and 11 (brightness, contrast and gain control inputs) pin 9 (horizontal blanking input) pin 10 (input clamping input) |
0 -0.1 -0.1 -0.1 -0.1 -0.1 -0.1 |
8.8 VP VP +0.7 VP VP + 0.7 VP + 0.7 |
V V V V V V V |
| Io(av) | average output current (pins 20, 17 and 14); note 1 | 0 | 50 | mA |
| IOM | peak output current (pins 20, 17 and 14) |
0 | 100 | mA |
| Ptot | total power dissipation | - | 1200 | mW |
| Tstg | storage temperature | -25 | +150 | °C |
| Tamb | operating ambient temperature | -20 | +70 | °C |
| Tj | junction temperature | -25 | +150 | °C |
| VESD | electrostatic handling for all pins; note 2 | -500 | +500 | V |
Notes
1. Signal amplitude of 50 mA black-to-white is possible if the average current (including blanking times and signal variation against time) does not exceed 50 mA. The maximum power dissipation of 1200 mW has to be considered.
2. Equivalent to discharging a 200 pF capacitor through a 0 series resistor.
