DESCRIPTIO

The LT®1813 is a low power, high speed, very high slew
rate operational amplifier with excellent DC performance.
The LT1813 features 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
characteristics of a current feedback amplifier.

The output drives a 100Ω load to ±3.5V with ±5V supplies.
On a single 5V supply, the output swings from 1.1V to 3.9V
with a 100Ω load connected to 2.5V. The amplifier is stable
with a 1000pF capacitive load which makes it useful in
buffer and cable driver applications.
