General Description
The EL2005 is a high-speed FET input buffer similar to
ELH0033 and EL2004 but with input specifications significant-
ly improved over the previous types The input stage employs a
cascode configuration to maintain constant input characteris-
tics over the full
g
10V input range The input looks like a 3 pF
capacitor to ground in almost all cases since the DC bias current
is constant with input voltage In sample and hold circuits this
results in an order of magnitude improvement in hold charac-
teristics Input offset voltage and offset voltage drift are also
improved a factor of two over previous types
These excellent DC characteristics are complemented by a wide
140 MHz bandwidth while the 1500 V
ms
slew rate and excel-
lent phase linearity of the ELH0033 family are preserved allow-
ing direct plug-in replacement for upgraded performance (For
even faster operation see EL2004 )
