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. functional block diagram R VIDEO IN R CLAMP CAP R GAIN ADJUST 3 16 V CC2 A1 A2 4 18 17 1 G VIDEO IN 5 G CLAMP CAP 7 A1 A2 15 G GAIN ADJUST 14 20 B VIDEO IN B CLAMP CAP 8 CLAMP GATE R CLAMP(+) G VIDEO OUT G CLAMP(+) A1 A2 9 B GAIN ADJUST 12 CONTRAST R VIDEO OUT 13 B VIDEO OUT 19 10 Contrast Control B CLAMP(+) 11 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.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All VCC terminals must be externally wired together to prevent internal damage during VCC power-on/-off cycles. 2. For operation above 25°C free-air temperature, derate linearly from 1.87 W (TA = 25°C) to 1.2 W (TA = 70°C). This equates to a derating factor of 15 mW/°C. 2 • POST OFFICE BOX 655303 DALLAS, TEXAS 75265 POST OFFICE BOX 1443 HOUSTON, TEXAS 77251−1443 •
