Dual/Quad 3mA, 100MHz,
750V/
s Operational Amplifiers
The LT
1813/LT1814 are dual and quad, low power, high
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
load to
3.5V with
5V supplies.
On a single 5V supply, the output swings from 1.1V to 3.9V
with a 100
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 the
8-pin MSOP and SO packages. The quad LT1814 is
available in the 14-pin SO and 16-pin SSOP package. A
single version, the LT1812, is also available (see separate
data sheet).
