General Description
The EL2130 is a wideband current mode feedback amplifier op-
timized for gains between
b
10 and
a
10 while operating on
g
5V power supplies Built using Elantec’s Complementary Bi-
polar process this device exhibits
b
3 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
Exhibiting a Differential Gain of 0 03% and a Differential
Phase of 0 1 at NTSC and PAL frequencies The EL2130 is an
excellent low cost solution to most video applications
In addition the EL2130 exhibits very low gain peaking typical-
ly below 0 1 dB to frequencies in excess of 40 MHz as well as 50
ns settling time to 0 2% making it an excellent choice for driv-
ing flash A D converters
The device is available in the plastic 8-lead narrow-body small
outline (SO) and the 8-pin mini DIP packages and operates
over the temperature range of 0 C to
a
75 C
Applications
Video amplifier
Video distribution amplifier
Residue amplifiers in ADC
Current to voltage converter
Coaxial cable driver
