The TLS1255 is a wide-band video preamplifier  
CONTRAST 12  
COLOR 13  
17 BLANKING  
system intended for high-resolution red-green-blue  
(RGB) color monitors with color-saturation control  
features. The saturation of a color refers to the  
degree of chroma or purity, or the degree of  
freedom from admixture with white. In addition to  
16 OSD_BLANKING  
15 B_CLAMP(+)  
CLAMP_GATE 14  
the RGB preamplifier function, the TLS1255 provides color-saturation control and gain control at the video  
system outputs. Each video amplifier (R, G, and B) contains a gain set for adjusting maximum system gain  
(A = 6 dB). The TLS1255 provides a digital level-operated contrast, brightness, color, and gain adjustment. The  
V
video-output stages from TLS1255 directly drive CRT power amplifiers.  
The system has been designed to operate from a 12-V supply with all digital level controls operating over a  
0-V to 4-V range to make the interface to serial digital buses possible. The TLS1255 also contains a blanking  
circuit that clamps the video output voltage to within 0.2 V of ground. The mixer circuit required for the OSD  
application is also integrated into the TLS1255, which makes the design of video boards and other applications  
easier.  
The TLS1255 is characterized for operation from 0°C to 70°C.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
