General Description

The EL2130 is a wideband current mode feedback amplifier optimized for gains between b10 and a10 while operating on g5V power supplies. Built using Elantec’s Complementary Bipolar process, this device exhibits b3 dB bandwidths in excess of 85 MHz at unity gain and 75 MHz at a gain of two. The EL2130 is capable of output currents in excess of 50 mA giving it the ability to drive either double or single terminated 50X coaxial cables.
