• description The LT6557 is a high speed triple video amplifier with an internal fixed gain of 2 and a programmable DC input bias voltage. The LT6557 is a high-speed video amplifier with an internal fixed gain of 2 and a programmable DC input bias voltage triple. This amplifier features a 400MHz 2VP-P signal bandwidth, 2200V/µs slew rate and a unique ability to drive heavy output loads to 0.8V of the supply rails, making the LT6557 ideal for a single 5V supply, wideband video application. The amplifier features a 400MHz 2VP-P signal bandwidth, 2200V/μs slew rate and unique ability to push a 0.8V output load on heavy power rails, making the LT6557 ideal for 5V single-supply, wideband video applications. With just one resistor, the inputs of all three amplifi ers can be programmed to a common voltage level, simplifying and reducing the need for external circuitry in the AC-coupled applications. With all three amplifiers ERS input is just a resistor that can be programmed to a common voltage level, simplifying and reducing the need for external circuitry in AC coupled applications. Without the programmable resistor, the input bias circuit becomes inactive, allowing the use of an external clamp circuit or direct coupled input. Without a programmable resistor, the input bias circuit becomes invalid, allowing the use of an external clamp circuit or direct coupling input. The LT6557 has separate power supply and ground pins for each amplifi er to improve channel separation and to ease power supply bypassing. The LT6557 features independent power and ground pins to improve channel separation and mitigate power supply bypass for each amplifier ER. The LT6557 provides uncompromised performance in many high speed applications where a low voltage, single supply is required. The LT6557 offers unmatched low voltage, and a single supply requires performance in many high-speed applications. The LT6557 is available in 16-lead SSOP and 5mm × 3mm DFN packages.
