General Description
The EL2004 is a very high-speed FET input buffer line driver
designed for unity gain applications at both high current (up to
100 mA) and at frequencies up to 350 MHz The 2500 V ms slew
rate and wide bandwidth ensures the stability of the circuit
when the EL2004 is used inside op amp feedback loops
Applications for the EL2004 include line drivers video buffers
wideband instrumentation and high-speed drivers for inductive
and capacitive loads The performance of the EL2004 makes it
an ideal buffer for video applications including input buffers for
flash A D converters and output buffers for video DACs Its
excellent phase linearity is particularly advantageous in digital
signal processing applications
Elantec facilities comply with MIL-I-45208A and are MIL-
STD-1772 certified Elantec’s Military devices comply with
MIL-STD-883B Revision C and are manufactured in our rigidly
controlled ultra-clean facilities in Milpitas California For ad-
