LT6402-20 300MHz的低失真，低噪声差分放大器/ ADC驱动器
特点
The LT6402-20 is a low distortion, low noise differential amplifier/ADC driver for use in applications from DC to 300MHz. LT6402-20是一种低失真，低噪声差分放大器/ ADC驱动从DC至300MHz的应用程序使用。 The LT6402-20 has been designed for ease of use, with minimal support circuitry required. LT6402-20已被设计为易于使用，所需的最小支持电路。 Exceptionally low input-referred noise and low distortion (with either single-ended or differential inputs) make the LT6402-20 an excellent solution for driving high speed 12-bit and 14-bit ADCs. 非常低的输入噪声和低失真（单端或差分输入），用于驱动高速12位和14位ADC的LT6402-20的一个极好的解决方案。 In addition to the normal unfiltered outputs (+OUT and –OUT), the LT6402-20 has a built-in 75MHz differential low pass filter and an additional pair of filtered outputs (+OUTFILTERED, –OUTFILTERED) to reduce external filtering components when driving high speed ADCs. 除了 正常过滤的输出（+ OUT和-OUT），LT6402-20，有一个内置的75MHz的差分低通滤波器和额外的滤波输出一双（+ OUTFILTERED，OUTFILTERED的），以减少驾驶时的外部滤波元件高速ADC。 The output common mode voltage is easily set via the V OCM pin, eliminating an output transformer or AC-coupling capacitors in many applications. 轻松设置输出共模电压通过V OCM引脚，消除输出变压器或交流耦合电容器在许多应用中。
The LT6402-20 is designed to meet the demanding requirements of communications transceiver applications. LT6402-20是专为满足通信收发器应用的苛刻要求。 It can be used as a differential ADC driver, a general-purpose differential gain block, or in other applications requiring differential drive.它可用于差分ADC驱动器，通用的差分增益块，或在其他应用程序需要差分驱动。 The LT6402-20 can be used in data acquisition systems required to function at frequencies down to DC. LT6402-20可用于在数据采集系统所需的功能在频率下降到直流。
The LT6402-20 operates on a 5V supply and consumes 30mA. LT6402-20 5V电源和，消耗30毫安。 It comes in a compact 16-lead 3mm × 3mm QFN package and operates over a –40ºC to 85ºC temperature range.它有一个紧凑的16引线3mm×3mm QFN封装，工作在-40°C至85°C的温度范围内。
