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 than other devices with comparable bandwidth. A power saving shutdown feature reduces supply current to 50 The circuit topology is a voltage feedback amplifier the slewing characteristics of a current feedback amplifier. The output drives a 100W load to ±3.5V with ±5V supplies. 

On a single 5V supply, the output swings from 1.1V to 3.9V with a 100W load connected to 2.5V. The amplifier is stable with a 1000pF capacitive load which makes it useful 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 70MHz gain bandwidth, see the LT1351 through LT1365
