DESCRIPTIO

Single/Dual/Quad 400MHz

Current Feedback Amplifier

The LT

400MHz current feedback amplifiers with an 800V/

µsslew

rate and the ability to drive up to 80mA of output current.

The LT1395/LT1396/LT1397 operate on all supplies from

a single 4V to

±6V. At ±5V, they draw 4.6mA of supply

current per amplifier.

The LT1395/LT1396/LT1397 are manufactured on Linear

Technology’s proprietary complementary bipolar process.

They have standard single/dual/quad pinouts and they are

optimized for use on supply voltages of

±5V.
