The LT
廬
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.
The LT1398/LT1399 operate on all supplies from a single
4V to
鹵6V.
The LT1399HV operates on all supplies from 4V
to
鹵7.5V.
Each amplifier draws 4.6mA when active. When disabled
each amplifier draws zero supply current and its output be-
comes 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 LT1398/LT1399/LT1399HV are manufactured on Lin-
ear Technology鈥檚 proprietary complementary bipolar pro-
cess. The LT1399/LT1399HV are pin-for-pin upgrades to
the LT1260 optimized for use on
鹵5V/鹵7.5V
supplies.
