3mA, 100MHz, 750V/µs

Operational Amplifier

with Shutdown

FEATURES

DESCRIPTIO

The LT^®1812 is a low power, high speed, very high slew

rate operational amplifier with excellent DC performance.

The LT1812 features reduced supply current, lower input

offset voltage, lower input bias current and higher DC gain

than other devices with comparable bandwidth. A power

saving shutdown feature reduces supply current to 50µA.

The circuit topology is a voltage feedback amplifier with

with a 1000pF capacitive load which makes it useful in

buffer and cable driver applications.

The LT1812 is manufactured on Linear Technology’s

advanced low voltage complementary bipolar process.

The dual version is the LT1813. For higher supply voltage

single, dual and quad operational amplifiers with up to

70MHz gain bandwidth, see the LT1351 through LT1365

data sheets.
