Typical Application
Description
The LT6558 is a high speed triple video amplifi er with an internal fi xed gain of 1 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 LT6558 ideal for a single 5V supply, wideband video application. With just one resistor, the inputs of all three amplifiers can be programmed to a common voltage level, simplifying and reducing the need for external circuitry in AC-coupled applications. Without the programming resistor, the input bias circuit becomes inactive, allowing the use of an external clamp circuit or direct coupled input.The LT6558 has separate power supply and ground pins for each amplifier to improve channel separation and to ease power supply bypassing.
The LT6558 provides uncompromised performance in many high speed applications where a low voltage, single supply is required. The LT6558 is available in 16-lead SSOP and 5mm × 3mm DFN packages.
