LT6411 650MHz Differential ADC Driver/Dual Selectable Gain Amplifier
The LT6411 is a dual amplifier with individually selectable gains of +1, +2 and –1. 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. 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. The LT6411 can be used on 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. 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
