• 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. LT6558是一个高速三路视频放大器ER 1内部连接，固定的增益可编程直流输入偏置电压。 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.该放大器具有一个400MHz 2VP-P的信号带宽，2200V/μs摆率和独特的能力，推动沉重的电源轨的0.8V输出负载，使LT6558在5V单电源，宽带视频应用的理想选择。 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. 所有三个放大器的输入，只需一个电阻，可以编程为一个共同的电压水平，简化和减少对外部电路的交流耦合应用的需要。 Without the programming resistor, the input bias circuit becomes inactive, allowing the use of an external clamp circuit or direct coupled input.无需编程电阻，输入偏置电路变为无效，允许使用一个外部钳位电路或直接耦合输入。 The LT6558 has separate power supply and ground pins for each amplifier to improve channel separation and to ease power supply bypassing. LT6558具有独立的电源供应器，每个放大器的管脚和接地管脚，提高声道分离度和缓解电源旁路。 The LT6558 provides uncompromised performance in many high speed applications where a low voltage, single supply is required. LT6558提供了无与伦比的低电压，单电源需要在许多高速应用的性能。 The LT6558 is available in 16-lead SSOP and 5mm × 3mm DFN packages. LT6558是在16引线SSOP和为5mm×3mm DFN封装。 应用
