• 描述 The LT6411 is a dual amplifier with individually selectable gains of +1, +2 and –1. The LT6411 is a separately selectable gain +1, +2, -1 dual amplifier. 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 The amplifier has excellent distortion performance for driving ADCs as well as high-speed applications such as excellent bandwidth, video, data transmission, and conversion rates. 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. Single-ended to differential conversion with a system gain of 2, specifically for direct configuration of one amplifier with +1 gain and other amplifier gains -1. The LT6411 can be used on split supplies as large as ±6V and on a single supply as low as 4.5V. The LT6411 can be used for split supplies as large as ±6V and on a single supply as low as 4.5V. Each amplifier draws only 8mA of quiescent current when enabled. When disabled, the output pins become high impedance and each amplifier draws less than 350μA. When disabled, the output pins become high impedance and each amplifier has a throw ratio of less than 350μA. 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. The LT6411 is Linear Technology's proprietary, low-voltage, free, bipolar process and manufacture in an ultra-compact 3mm×3mm, 16-PIN QFN package
