LM1205A

The LM1205A is designed as one kind of 130 MHz RGB video amplifier system with blanking that can be used in (1)high resolution RGB CRT monitors; (2)video AGC amplifiers; (3)wideband amplifiers with gain and DC offset controls; (4)interface amplifiers for LCD or CCD systems. This device contains three gated single ended input black level clamp comparators for brightness control, three matched DC controlled attenuators for contrast control, and three DC controlled sub-contrast attenuators providing gain trim capability for white balance.

Features of the LM1205A are:(1)three wideband video amplifiers 130 MHz @ b3 dB (4 Vpp output);(2)matched (+/-0.1 dB or 1.2%) attenuators for contrast control;(3)three externally gated single ended input comparators for cutoff and brightness control;(4)provisions for individual gain control (Drive) of each video amplifier;(5)0V to 4V, high input impedance DC contrast control (l40 dB range);(6)0V to 4V, high input impedance DC drive control (+/-3 dB range);(7)capable of 7 VPP output swing (slight reduction in bandwidth);(8)output stage blanking;(9)output stage directly drives most hybrid or discrete CRT drivers.

The absolute maximum ratings of the LM1205A can be summarized as:(1)supply voltage (Vcc) pins 3, 11, 22, 23, 25:13.5 V;(2)peak video output source current (any one amp) pins 17, 20 or 26:28 mA;(3)voltage at any input pin (VIN):Vcc >/= VIN >/= GND;(4)power dissipation (PD) (above 25 derate):2.5 W;(5)thermal resistance:50/W;(6)junction temperature:150;(7)ESD susceptibility:2 kV;(8)storage temperature:-65 to 150;(9)lead temperature (soldering, 10 sec.):265.
