LT1207

Dual 250mA/60MHz

Current Feedback Amplifier

DESCRIPTIO

EATURE

The LT^®1207 is a dual version of the LT1206 high speed

current feedback amplifier. Like the LT1206, each CFA in

thedualhasexcellentvideocharacteristics:60MHzband-

width, 250mA minimum output drive current, 400V/µs

minimum slew rate, low differential gain (0.02% typ) and

low differential phase (0.17° typ). The LT1207 includes a

pin for an optional compensation network which stabi-

lizes the amplifier for heavy capacitive loads. Both ampli-

fiershavethermalandcurrentlimitcircuitswhichprotect

againstfaultconditions.ThesecapabilitiesmaketheLT1207

well suited for driving difficult loads such as cables in video

or digital communication systems.

Cable Drivers

Operation is fully specified from ±5V to ±15V supplies.

Supply current is typically 20mA per amplifier. Two

micropower shutdown controls place each amplifier in a

high impedance low current mode, dropping supply

current to 200µA per amplifier. For reduced bandwidth

applications, supply current can be lowered by adding a

resistor in series with the Shutdown pin.

The LT1207 is manufactured on Linear Technology's

complementary bipolar process and is available in a low

thermal resistance 16-lead SO package.
