LT1398/LT1399/LT1399HV

Low Cost Dual and Triple

300MHz Current Feedback

Amplifiers with Shutdown

FEATURES

DESCRIPTIO

The LT^®1399 and LT1399HV contain three independent

300MHz current feedback amplifiers, each with a shut-

down pin. The LT1399HV is a higher voltage version of the

LT1399. The LT1398 is a two amplifier version of the

LT1399.

■

300MHz Bandwidth on ±5V (A_V= 1, 2 and –1)

■

0.1dB Gain Flatness: 150MHz (A_V= 1, 2 and –1)

■

Completely Off in Shutdown, 0µA Supply Current

High Slew Rate: 800V/µs

Wide Supply Range:

■

±2V(4V) to ±6V(12V) (LT1398/LT1399)

±2V (4V) to ±7.5V (15V) (LT1399HV)

The LT1398/LT1399 operate on all supplies from a single

4Vto±6V.TheLT1399HVoperatesonallsuppliesfrom4V

to ±7.5V.

■

80mA Output Current

■

Low Supply Current: 4.6mA/Amplifier

Fast Turn-On Time: 30ns

Fast Turn-Off Time: 40ns
