Linear Technology LT1812

The LT1812 features reduced supply current, lower input offset voltage, lower input bias current and higher DC gain than other devices with comparable bandwidth. 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.

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.
