Linear Technology
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. The circuit topology is a voltage feedback amplifier with the slewing characteristics of a current feedback amplifier.
