  The LT®1399 and LT1399HV contain three independent 300MHz current feedback amplifiers, each with a shutdown pin.®The LT 1399 and LT1399HV contain three independent 300MHz current feedback amplifiers, each with a shutdown pin. The LT1399HV is a higher voltage version of the LT1399.The LT1399HV is a higher voltage version of the LT1399. The LT1398 is a two amplifier version of the LT1399.LT1399 version of the LT1399 with two amplifiers.

  The LT1398/LT1399 operate on all supplies from a single 4V to 6V.The LT1398/LT1399 operate on all supplies by a single 4V 6V. The LT1399HV operates on all supplies from 4V to 7.5V.The LT1399HV operates from 4V to 7.5V supply.

  Each amplifier draws 4.6mA when active.Each amplifier draws 4.6 mA when active. When disabled each amplifier draws zero supply current and its output becomes high impedance.When disabled people consume zero supply current per amplifier, their output becomes high impedance. The amplifiers turn on in only 30ns and turn off in 40ns, making them ideal in spread spectrum and portable equipment applications.The amplifiers are turned on for only 30ns and turned off at 40ns, making them ideal for spread spectrum and portable device applications.

  The LT1398/LT1399/LT1399HV are manufactured on Linear Technology's proprietary complementary bipolar process.Manufactured in the LT1398/LT1399/LT1399HV proprietary complementary bipolar process. The LT1399/LT1399HV are pin-for-pin upgrades to the LT1260 optimized for use on ±5V/ 7.5V supplies.The LT1399/LT1399HV pins are optimized for pin upgrades to the LT1260±5V/7.5V
