description  
The TLS1233 is a 100-MHz wide-band video preamplifier system intended for mid-to-high-resolution RGB  
(red-green-blue) color monitors. Each video amplifier (R, G, and B) contains a gain set for adjusting maximum  
system gain (A = 7.8 V/V). The TLS1233 provides digital level-operated contrast, brightness, and gain  
V
adjustment control. 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. Provided in a 20-pin plastic dual-in-line package (DIP), the TLS1233  
integrates most of the external components required to accommodate the video system.  
The TLS1233 operates from a 12-V supply and contains an internal input bias voltage. Also, the TLS1233  
contains the feedback resistor required between output and CLAMP(–) for dc level holding. The device is  
characterized for operation from 0°C to 70°C.
