DESCRIPTION
650MHz Differential ADC
Driver/Dual Selectable
Gain Amplier
The LT
6411 is a dual amplier with individually selectable
gains of +1, +2 and –1. The ampliers have excellent dis-
tortion 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 straight-
forward by conguring one amplier with a gain of +1
and the other amplier 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 amplier draws only 8mA of quiescent current when
enabled. When disabled, the output pins become high
impedance and each amplier draws less than 350A.
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.
