DESCRIPTION
The LT
quad voltage feedback amplifi ers that feature 100MHz
gain-bandwidth product, 450V/μs slew rate and 50mA
output current. These amplifi ers have an input range that
includes ground and an output that swings within 60mV
of either supply rail, making them well suited for single
supply operation.
These amplifi ers maintain their performance for supplies
from 2.7V to 12.6V and are specifi ed at 3V, 5V and ±5V.
The inputs can be driven beyond the supplies without
damage or phase reversal of the output. Isolation between
channels is high, over 90dB at 10MHz.
The LT6205 is available in the 5-pin SOT-23, and the LT6206
is available in an 8-lead MSOP package with standard op
amp pin-outs. For compact layouts the quad LT6207 is
available in the 16-pin SSOP package. These devices are
specifi ed over the commercial, industrial, and automotive
temperature ranges.

... In general, use feedback resistors less. Capacitive Load limits the current IN The LT6205/LT6206/LT6207 are optimized for wide band- width video applications. They can drive a capacitive load of 20pF in a unity-gain confi guration. When driving a larger capacitive load, a resistor of 10Ω to 50Ω should be connected between the output and the capacitive load to avoid ringing or oscillation ...
