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 (AV = 7.8 V/V). The TLS1233 provides digital level-operated
contrast, brightness, and gain
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.
