June 29, 2015 400MHz Slew Rate Enhanced, Rail-to-Rail Output Gain Block Features The ISL55033 is a triple rail-to-rail output gain block with a
-3dB bandwidth of 400MHz and slew rate of 2350V/Вµs into a
150пЃ— load. The ISL55033 has a fixed gain of +2. The inputs
are capable of sensing ground. The outputs are capable of
swinging to 0.45V to either rail through a 150О© resistor
connected to V+/2. 400MHz -3dB bandwidth 2350V/Вµs typ slew rate, RL = 150О©пЂ to V+/2 Single-supply operation from +3V to +5.5V Rail-to-rail output The ISL55033 is designed for general purpose video
applications. The part includes a fast-acting global
disable/power-down function. Input ground sensing Fast 25ns disable time Pb-free (RoHS compliant) The ISL55033 is available in a 12 Ld TQFN package. Operation
is specified over the -40В°C to +85В°C temperature range. Applications Video amplifiers Set-top boxes Video distribution Pin Configuration 2 IN+_3 3 EN V+_OUTPUT
