LT1395/LT1396/LT1397

Single/Dual/Quad 400MHz

Current Feedback Amplifier

FEATURES

DESCRIPTIO

The LT^®1395/LT1396/LT1397 are single/dual/quad

400MHzcurrentfeedbackamplifierswithan800V/µsslew

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

■

400MHz Bandwidth on ± 5V (A_V= 1)

■

350MHz Bandwidth on ± 5V (A_V= 2, –1)

■

0.1dB Gain Flatness: 100MHz (A_V= 1, 2 and –1)

■

High Slew Rate: 800V/µs

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 LT1395CS6 also adds a shut-

down pin. When disabled, the LT1395CS6 draws virtually

zero supply current and its output becomes high imped-

ance. TheLT1395CS6willturnoninonly30nsandturnoff

in 40ns, making it ideal in spread spectrum and portable

equipment applications.

■

Wide Supply Range: ±2V(4V) to ±6V(12V)

■

80mA Output Current

■

Low Supply Current: 4.6mA/Amplifier

LT1395: SO-8, TSOT23-5 and TSOT23-6 Packages

LT1396: SO-8, MSOP and Tiny 3mm × 3mm ×

0.75mm DFN-8 Packages

LT1397: SO-14, SSOP-16 and Tiny 4mm × 3mm ×

0.75mm DFN-14 Packages

For space limited applications, the LT1395 is available in

TSOT-23 packages, the LT1396 is available in a tiny 3mm

× 3mm × 0.75mm dual fine pitch leadless DFN package,

and the LT1397 is available in a tiny 4mm × 3mm ×

0.75mm DFN package.
