LT1812 3mA, 100MHz, 750V/s Operational Ampli er with Shutdown FEATURES DESCRIPTION n 100MHz Gain Bandwidth The LT 1812 is a low power, high speed, very high slew n 750V/s Slew Rate rate operational ampli er with excellent DC performance. n 3.6mA Maximum Supply Current The LT1812 features reduced supply current, lower input n 50A Supply Current in Shutdown offset voltage, lower input bias current and higher DC gain n 8nV/Hz Input Noise Voltage than other devices with comparable bandwidth. A power n Unity-Gain Stable saving shutdown feature reduces supply current to 50A. n 1.5mV Maximum Input Offset Voltage The circuit topology is a voltage feedback ampli er with the n 4A Maximum Input Bias Current slewing characteristics of a current feedback ampli er. n 400nA Maximum Input Offset Current The output drives a 100 load to 3.5V with 5V supplies. n 40mA Minimum Output Current, V = 3V OUT On a single 5V supply, the output swings from 1.1V to n 3.5V Minimum Input CMR, V = 5V S 3.9V with a 100 load connected to 2.5V. The ampli er n 30ns Settling Time to 0.1%, 5V Step is stable with a 1000pF capacitive load which makes it n Speci ed at 5V, Single 5V Supplies useful in buffer and cable driver applications. n Operating Temperature Range: 40C to 85C n The LT1812 is manufactured on Linear Technologys Low Pro le (1mm) SOT-23 (ThinSOT ) advanced low voltage complementary bipolar process. and S8 Packages The dual version is the LT1813.
