The LT1812 Features reduced supply current, lower input offset voltage, lower input bias current and higher DC gain than other devices with parable 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. 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 1000p F capacitive load which makes it useful in buffer and cable driver applications. The LT1812 is manufactured on Linear Technology’s advanced low voltage plementary 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. , LTC and LT are registered trademarks of Linear Technology Corporation.
