Overview
EL2009C EL2009C 90 MHz 1 Amp Buffer Amplifier Features  High slew rate 3000 V ms  Wide bandwidth 125 MHz RL e 50X 90 MHz RL e 10X  Output current 1A continuous  Output impedance 1X  Short circuit protected  Power package with isolated metal tab General Description The EL2009 is a patented high speed bipolar monolithic buffer amplifier designed to provide currents over 1 amp at high frequencies while drawing 40 mA of quiescent supply current The EL2009’s 3000 V ms slew rate and 90 MHz bandwidth driving a 10X load insures stability in fast op amp feedback loops Elantec has applied for patents on unique circuitry within the EL2009 Used as an open loop buffer the EL2009’s low output impedance (1X) gives a gain of 0 99 when driving a 100X load and 0 9 driving a 10X load The EL2009 has an output short circuit current limit which will protect the device under both a DC fault condition and AC operation with reactive loads The EL2009 is constructed using Elantec’s proprietary Complementary Bipolar process that produces PNP and NPN transistors with essentially identical AC and DC characteristics In the EL2009 the Complementary Bipolar process also insulates the package’s metal heat sink tab from all supply voltages Therefore the tab may be mounted to an external heat sink or the chassis without an insulator The EL2009CT is specified for operation over the 0 C to a 75 C temperature range and is provided in a 5-lead TO-220 plastic power package Applications       Video distribution amplifier Fast op amp booster Flash converter driver Motor driver Pulse transformer driver A T E pin driver Ordering Information Part No Temp Range Package Outline TO-220 MDP0028 EL2009CT 0 C to a 75 C Connection Diagram 5-Pin TO-220 Simplified Schematic December 1995 Rev C 2009 – 1 Top View 2009 – 2 Manufactured under U S Patent No 4 833 424 and 4 827 223 and U K Patent No 2217134 Note All information contained in this data sheet has been carefully checked and is believed to b...
