The TLS1215 is a wide-band video preamplifier  
system intended for high-resolution RGB  
(red-green-blue) color monitors with blanking  
control features. Each video amplifier (R, G, and  
B) contains a gain set for adjusting maximum  
system gain. The TLS1215 provides digital

level-operated contrast, brightness, and gain adjustment. All the control inputs offer high input impedance and  
an operation range from 0 V to 4 V for easy interface to the serial digital buses. The TLS1215 also contains a  
blanking circuit, which clamps the video output voltage during blanking period to as low as 0.2 V above ground.  
The device operates from a 12-V supply. The TLS1215 is characterized for operation from 0°C to 70°C.
