• 描述 The LT6411 is a dual amplifier with individually selectable gains of +1, +2 and –1. LT6411是一个单独可选增益+1，+2，-1双放大器。 The amplifiers have excellent distortion performance for driving ADCs as well as excellent bandwidth and slew rate for video, data transmission and other high speed applications.放大器具有优良的失真性能，用于驱动ADC以及出色的带宽，视频，数据传输等高速应用和转换率。 Single-ended to differential conversion with a system gain of 2 is particularly straightforward by configuring one amplifier with a gain of +1 and the other amplifier with a gain of –1.系统增益为2的单端至差分转换，特别是直接配置一个放大器增益为+1和其他放大器增益-1。 The LT6411 can be used on split supplies as large as ±6V and on a single supply as low as 4.5V.的LT6411可用于分离电源为±6V大作为低如4.5V的单电源。 Each amplifier draws only 8mA of quiescent current when enabled.启用时，每个放大器仅消耗静态电流8毫安的。 When disabled, the output pins become high impedance and each amplifier draws less than 350µA.禁用时，输出引脚变为高阻抗，每个放大器的投篮比350μA以下。 The LT6411 is manufactured on Linear Technology's proprietary, low voltage, complimentary, bipolar process and is available in the ultra-compact, 3mm × 3mm, 16pin QFN package. LT6411是凌力尔特公司专有的，低电压，免费，双极工艺和制造，是在超小型的3mm×3mm的，16PIN的QFN封装
