500MHz, 2200V/µs Gain of 2,  
Single Supply Triple Video  
Amplifier with Input Bias Control  
FEATURES  
DESCRIPTION  
The LT®6557 is a high speed triple video amplifier with an  
internal fixed gain of 2 and a programmable DC input bias  
–3dB Small-Signal Bandwidth: 500MHz  
–3dB 2V Large-Signal Bandwidth: 400MHz

Fixed Gain of 2, No External Resistors Required  
bandwidth, 2200V/µs slew rate and a unique ability to  
drive heavy output loads to 0.8V of the supply rails, mak-  
ingtheLT6557idealforasingle5Vsupply,widebandvideo  
application. With just one resistor, the inputs of all three  
amplifierscanbeprogrammedtoacommonvoltagelevel,  
simplifying and reducing the need for external circuitry in  
the AC-coupled applications. Without the programmable  
resistor,theinputbiascircuitbecomesinactive,allowingthe  
use of an external clamp circuit or direct coupled input.  
AC Coupling with Programmable DC Input Bias  
Output Swings to 0.8V of Supply Rails  
Full Video Swing with 5V Single Supply  
Diff Gain: 0.02%  
Diff Phase: 0.05°  
Enable/Shutdown Pin  
High Output Current: 100mA  
Supply Range: 3V to 7.5V  
Operating Temperature Range: –40°C to 85°C  
TheLT6557hasseparatepowersupplyandgroundpinsfor  
each amplifier to improve channel separation and to ease  
power supply bypassing. The LT6557 provides uncom-  
promised performance in many high speed applications  
where a low voltage, single supply is required.
