EL5160 Overview
A current-feedback amplifier (CFA) is a type of operational amplifier whose architecture senses error current rather than error voltage at its input stage. In the power-management and signal-chain hierarchy, the CFA sits under the amplifier family alongside voltage-feedback op amps, but its closed-loop bandwidth is largely set by the feedback resistor rather than the gain-bandwidth product, allowing the EL5160 to maintain near-constant 200MHz bandwidth across useful gain settings.
Key differentiating specifications include the 200MHz -3dB bandwidth, an extremely low 0.75mA supply current per amplifier, and an enable function (EL5160 variant) that permits power savings in multiplexed or strobed video signal paths. The output stage is capable of driving 50-ohm loads toward both supply rails, which is unusual for a micropower amplifier and simplifies direct drive of video cables and monitor inputs.
Architecturally, the current-feedback topology yields high slew rate and fast settling without the classic gain-bandwidth trade-off of voltage-feedback designs. The family also includes the EL5161 (single, no enable), EL5260/EL5261 (dual) and EL5360 (quad), letting designers scale channel count while reusing the same 200MHz/0.75mA performance envelope.
Typical applications include high-speed video signal distribution, CRT/LCD monitor front ends, video switching and buffering, and portable or battery-powered instrumentation where the 0.75mA quiescent draw extends battery life.
Design considerations: because bandwidth depends on the feedback resistor, use the datasheet-recommended RF value; deviations directly shift the -3dB corner and peaking behavior.

Typical Applications
EL5160 is suitable for 6 applications: High-Speed Video Buffering, Monitor Front-End Signal Conditioning, Video Switching and Multiplexing, Portable and Battery-Powered Instrumentation, Industrial Video and Display Interconnects, Video ADC Input Driver.
High-Speed Video Buffering
The EL5160 is well suited to high-speed video buffering because its 200MHz -3dB bandwidth comfortably covers standard- and high-definition video signals, while its 0.75mA supply current keeps total system power low in multi-channel video chains. In a typical circuit the amplifier is configured as a non-inverting unity- or gain-of-two buffer between a video DAC or mux output and a 75-ohm back-terminated cable. Because the current-feedback topology holds bandwidth largely independent of closed-loop gain at these settings, the video response stays flat without external compensation. The ability to drive 50-ohm-class loads toward both rails means no additional line driver stage is needed, reducing board area and signal-path complexity in monitor and video distribution designs.

Monitor Front-End Signal Conditioning
CRT and LCD monitor front ends benefit directly from the EL5160's combination of bandwidth and power efficiency. The 200MHz -3dB bandwidth preserves RGB video edge rates and reduces overshoot and ringing when the amplifier is placed after cable equalization or switching stages. The datasheet-quoted ability to drive 50-ohm loads toward both rails allows the EL5160 to directly drive monitor input networks without a separate output buffer. Meanwhile, the 0.75mA per-amplifier consumption is attractive in monitors where several amplifier channels operate simultaneously; scaling with the dual EL5260 or quad EL5360 keeps per-channel power identical. Designers should use the datasheet-recommended feedback resistor value to keep peaking and bandwidth within specification across temperature, -40C to +85C.
Recommended
Video Switching and Multiplexing
The EL5160's enable pin makes it a natural fit for video switching and multiplexing systems where unused channels are powered down. Toggling enable to shut off a channel saves that channel's share of the 0.75mA operating current and also isolates the signal path, preventing off-channel feedthrough into the active video line. In a muxed video router, each EL5160 can sit immediately after a switch element to restore drive strength and isolate switch charge-injection from the output cable. Because the part restores full 200MHz bandwidth within its settling characteristics when re-enabled, switching transients remain short relative to video line timing. For multi-output routers, pairing single EL5160 units per output with the datasheet-recommended feedback resistor network keeps every output's bandwidth matched.
Recommended
Portable and Battery-Powered Instrumentation
In battery-powered instruments that must process fast signals, the EL5160 offers a rare combination: 200MHz bandwidth at only 0.75mA supply current. Most wideband voltage-feedback amplifiers with comparable bandwidth draw tens of milliamps, so replacing one with the EL5160 can cut the analog front-end current budget by an order of magnitude, directly extending battery runtime. Typical circuits include signal buffering ahead of an ADC driver, cable-driving in handheld test probes, and conditioning fast edges in portable communications test gear. The enable function supports duty-cycled operation, shutting the amplifier down between measurements. Engineers should verify supply voltage range and output drive requirements against the datasheet electrical tables, since those values were not captured in the sources used for this page.

Industrial Video and Display Interconnects
Industrial display and machine-vision interconnects operate over the EL5160's full -40C to +85C industrial temperature range, making the part appropriate for factory-floor monitors, signage controllers and vision-system camera links. The 200MHz bandwidth supports high pixel-clock video standards without excessive edge degradation over back-terminated cable runs, and the 50-ohm load-driving output simplifies the transmit side of point-to-point coax connections. The current-feedback architecture also tolerates a range of closed-loop gains, allowing one design to serve multiple cable lengths by adjusting gain with a single resistor. In multi-output industrial repeaters, the quad EL5360 consolidates four channels in a 16-lead SOIC or QSOP package, sharing the same 0.75mA-per-channel power profile as the single EL5160.
Recommended
Video ADC Input Driver
The EL5160 works as a fast video ADC input driver where the converter needs a low-impedance, wideband source. Placed between the video signal source and the ADC input, the EL5160 isolates the converter's dynamic input current from the source impedance, preventing settling errors at high pixel rates. Its 200MHz -3dB bandwidth ensures the drive network remains flat through the ADC's analog input band, and the 0.75mA supply current matters in multi-converter capture cards. A series resistor between the amplifier output and the ADC input, plus a shunt capacitor at the pin, forms the usual isolation network recommended in high-speed amplifier application practice; component values should be tuned against the specific ADC's input model and the EL5160 datasheet-recommended feedback resistor to preserve bandwidth and settling.

Design Notes
Current-feedback amplifiers like the EL5160 set closed-loop bandwidth primarily through the feedback resistor (RF), not the gain-setting resistor. Always start with the datasheet-recommended RF value from the FN7387 datasheet; reducing RF below the recommended minimum increases peaking and can cause instability or ringing on video edges, while increasing RF rolls off the 200MHz bandwidth. Keep the inverting-node trace short and low inductance, since stray capacitance at the inverting input directly degrades phase margin.
The EL5160 draws only 0.75mA per amplifier, so supply decoupling requirements are modest, but wideband amplifiers still need a 0.1uF ceramic capacitor placed within a few millimeters of each supply pin, plus a bulk capacitor per board region. Use the enable pin to power down unused channels in multiplexed designs; this saves the per-channel current and reduces crosstalk from idle stages. Confirm the allowable supply voltage range against the datasheet absolute maximum ratings before finalizing the rail design.
Do not treat the EL5160 as pin-compatible with the EL5161: the EL5160 uses 6-lead SOT-23 or 8-lead SOIC with an enable pin, while the EL5161 uses 5-lead SOT-23 or SC-70 without enable. Substituting across the family requires footprint and netlist changes. Also verify load conditions when driving long cables: although the output can drive 50-ohm-class loads toward both rails, sustained heavy loads increase dissipation beyond the small SOT-23 thermal capability, so check junction temperature at worst-case video levels.
