FEATURES  
DESCRIPTION  
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.

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.

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.
