Dual/Quad 3mA, 100MHz,

750V/

µs Operational Amplifiers

The LT

speed, very high slew rate operational amplifiers with

excellent DC performance. The LT1813/LT1814 feature

reduced supply current, lower input offset voltage, lower

input bias current and higher DC gain than other devices

with comparable bandwidth. The circuit topology is a

voltage feedback amplifier with the slewing characteris-

tics of a current feedback amplifier.

The output drives a 100

Ωloadto ±3.5Vwith ±5Vsupplies.

On a single 5V supply, the output swings from 1.1V to 3.9V

with a 100

Ω load connected to 2.5V. The amplifiers are

stable with a 1000pF capacitive load making them useful

in buffer and cable driver applications.

The LT1813/LT1814 are manufactured on Linear

Technology’s advanced low voltage complementary bipo-

lar process. The LT1813 dual op amp is available in

8-pin MSOP, SO and 3mm x 3mm low profile (0.8mm)

dual fine pitch leadless packages (DFN). The quad LT1814

is available in 14-pin SO and 16-pin SSOP packages. A

single version, the LT1812, is also available (see separate

data sheet).
