EL5202, EL5203 FN7331
Rev 9.00
January 17, 2014 400MHz Slew Enhanced VFAs
The EL5202 and EL5203 are dual, high-speed VFAs based on a
CFA architecture. This gives the typical high slew rate benefits
of a CFA family along with the stability and ease of use
associated with the VFA type architecture. With slew rates of
3500V/Вµs, these devices enable the use of voltage feedback
amplifiers in a space where the only alternative has been
current feedback amplifiers. This family also includes single,
dual, and triple versions with 750MHz bandwidths; please see
the EL5104 through EL5304 data sheet for details.
Both devices operate on single 5V or В±5V supplies from
minimum supply current. The EL5202 also features an output
enable function, which can be used to put the output in to a
high-impedance mode. This allows the outputs of multiple
amplifiers to be tied together for use in multiplexing
applications.
Typical applications for these families include cable driving,
filtering, A/D and D/A buffering, multiplexing and summing
within video, communications, and instrumentation designs.
