The EL5x02 and EL5x03 families represent high-speed VFAs based on a CFA amplifier 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/µs, this family of devices enables the use of voltage feedback amplifiers in a space where the only alternative has been current feedback amplifiers. This family will also be available in single, dual, and triple versions, with 200MHz, 400MHz, and 750MHz versions. These are all available in single, dual, and triple versions.

Both families operate on single 5V or ±5V supplies from minimum supply current. EL5x02 also features an output enable function, which can be used to put the output in to a high-impedance mode. This enables the outputs of multiple amplifiers to be tied together for use in multiplexing applications.

Typical applications for these families will include cable driving, filtering, A-to-D and D-to-A buffering, multiplexing and summing within video, communications, and instrumentation designs.
