LT6557 Datasheet | Linear Technology

.. LT6557 500MHz, 2200V/µs Gain of 2, Single Supply Triple Video Amplifier with Input Bias Control DESCRIPTION The LT®6557 is a high speed triple video amplifier with an internal fixed gain of 2 and a programmable DC input bias voltage. 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. With just one resistor, the inputs of all three amplifiers can be programmed to a mon voltage level, simplifying and reducing the need for external circuitry in the AC-coupled applications. Without the programmable resistor, the input bias circuit bees inactive, allowing the use of an external clamp circuit or direct coupled input. The LT6557 has separate power supply and ground pins for each amplifier to improve channel separation and to ease power supply bypassing. The LT6557 provides unpromised performance in many high speed applications where a low voltage, single supply is required. The LT6557 is available in 16-lead SSOP and 5mm × 3mm DFN packages. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
