400MHz Slew Enhanced VFAs
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.
Features
• Operates off 3V, 5V, or ±5V applications
• Power-down to 0µA (EL5x02)
• -3dB bandwidth = 400MHz
• ±0.1dB bandwidth = 50MHz
• Low supply current = 5mA
• Slew rate = 3500V/µs
• Low offset voltage = 5mV max
• Output current = 140mA
• AVOL = 2000
• Diff gain/phase = 0.01%/0.01°
Pb-Free plus anneal available (RoHS compliant)
Applications
• Video amplifiers
• PCMCIA applications
• A/D drivers
• Line drivers
• Portable computers
• High speed communications
• RGB applications
• Broadcast equipment
• Active filtering
1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

NOTES:
1. All AC tests are performed on a “warmed up” part, except slew rate, which is pulse tested.
2. Standard NTSC signal = 286mVP-P, f = 3.58MHz, as VIN is swept from 0.6V to 1.314V.RL is DC coupled.
3. Disable/Enable time is defined as the time from when the logic signal is applied to the ENABLE pin to when the supply current has reached half
its final value.
