polar process, this device exhibits 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.

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.
Applications
# Video amplifier
# Video distribution amplifier
# Residue amplifiers in ADC
# Current to voltage converter
# Coaxial cable driver
The device is available in the plastic 8-lead narrow-body small
outline (SO) and the 8-pin mini DIP packages, and operates
a
over the temperature range of 0 C to 75 C.
