LT6557 500MHz, 2200V/s Gain of 2, Single Supply Triple Video Ampli er with Input Bias Control FEATURES DESCRIPTION 3dB Small-Signal Bandwidth: 500MHz The LT 6557 is a high speed triple video ampli er with an 3dB 2V Large-Signal Bandwidth: 400MHz internal xed gain of 2 and a programmable DC input bias P-P Slew Rate: 2200V/s voltage. This ampli er features a 400MHz 2V signal P-P Fixed Gain of 2, No External Resistors Required bandwidth, 2200V/s slew rate and a unique ability to AC Coupling with Programmable DC Input Bias drive heavy output loads to 0.8V of the supply rails, mak- Output Swings to 0.8V of Supply Rails ing the LT6557 ideal for a single 5V supply, wideband video Full Video Swing with 5V Single Supply application. With just one resistor, the inputs of all three Diff Gain: 0.02% ampli ers can be programmed to a common voltage level, Diff Phase: 0.05 simplifying and reducing the need for external circuitry in Enable/Shutdown Pin the AC-coupled applications. Without the programmable High Output Current: 100mA resistor, the input bias circuit becomes inactive, allowing the Supply Range: 3V to 7.5V use of an external clamp circuit or direct coupled input. Operating Temperature Range: 40C to 85C The LT6557 has separate power supply and ground pins for Available in 16-Lead SSOP and 5mm 3mm DFN each ampli er to improve channel separation and to ease Packages power supply bypassing. The LT6557 provides uncom- promised performance in many high speed applications APPLICATIONS where a low voltage, single supply is required. LCD Video Projectors The LT6557 is available in 16-lead SSOP and 5mm 3mm RGB HD Video Ampli ers DFN packages.
