EL5306 Overview
A fixed gain amplifier is a type of high-speed voltage feedback amplifier in which the gain-setting network is internal, eliminating external gain resistors and the layout parasitics and tolerance errors they introduce. Within the signal-chain hierarchy, it sits between general-purpose op amps and dedicated video buffers, and belongs to the broader family of high-speed amplifiers and analog signal conditioning ICs.
Key features include a 350MHz bandwidth tuned for high-speed video and monitor applications, internal gain-setting resistors configurable in gains of +1, -1 or +2, a power-saving enable/disable function that reduces supply current to 25uA typical per amplifier, and very low differential gain and phase of 0.02% and 0.04 degrees while driving 150 ohm loads at a gain of 2.
Technically, the EL5306 uses special internal circuitry that reduces the variation of output impedance with output current, which directly delivers the excellent dG/dP video performance. Its low 1.5mA per-amplifier supply current combined with 350MHz bandwidth makes it well suited to portable, handheld, and battery-powered equipment, per the manufacturer datasheet. The device operates over the industrial temperature range to +85C.
Typical applications include high-resolution video signal distribution in monitors, video line driving, and multi-channel high-bandwidth signal conditioning in portable test and communication equipment.
A key design consideration: the amplifier is specified for supply spans of at least 5V and up to 11V; operate it within 5V to 10V single-supply or ±2.5V to ±5V dual-supply to maintain rated bandwidth and video performance.

Typical Applications
EL5306 is suitable for 6 applications: High-Speed Video Distribution, Portable and Battery-Powered Equipment, Computer Monitors and Display Interfaces, Industrial Video and Vision Systems, Test and Measurement Signal Conditioning, Communication and Networking Video Ports.
High-Speed Video Distribution
The EL5306 is explicitly designed for high-speed video and monitor applications, per the Renesas datasheet. Its 350MHz bandwidth comfortably supports high-resolution RGB video signals, and the internal gain resistors in +1, -1 or +2 configurations let designers implement video line drivers, buffers, or inverting stages without external precision resistors that add tolerance error. The 0.02% differential gain and 0.04 degree differential phase while driving 150 ohm loads at gain 2 ensure broadcast-quality signal fidelity across all three channels, making it well suited to RGB monitor interfaces and multi-channel video distribution where channel-to-channel matching matters.
Recommended
Portable and Battery-Powered Equipment
The datasheet directly identifies portable, handheld, and battery-powered equipment as the target environment for the EL5106/EL5306 family. At 1.5mA supply current per amplifier - 4.5mA for all three channels - the EL5306 delivers 350MHz bandwidth at a fraction of the power of typical high-speed amplifiers. The enable function cuts current to 25uA per amplifier when the video path is idle, allowing aggressive duty-cycling in battery products. Compared with the EL5191 (9mA) or similar GHz-class amplifiers, the EL5306 can extend battery life several-fold in video-equipped handheld instruments and portable test gear.
Recommended
Computer Monitors and Display Interfaces
Monitor front-end circuitry requires three matched high-bandwidth channels for RGB signals, which maps directly onto the triple EL5306. The reduced output impedance variation - the special circuitry highlighted in the datasheet - is what enables the 0.02%/0.04 degree dG/dP figures when driving 150 ohm doubled-terminated video loads at gain 2, which is the standard video distribution topology. Internal gain resistors also remove an entire class of board-level calibration issues in high-volume monitor production, and the 5V to 10V single-supply range aligns with typical monitor power architectures.
Recommended
Industrial Video and Vision Systems
Machine-vision and industrial video chains operate over the industrial temperature range to +85C that the EL5306 is rated for, per the datasheet. The triple amplifier handles RGB camera signals with gain set internally to +2 to drive back-terminated coax or 150 ohm video loads, while the ±2.5V to ±5V dual-supply capability interfaces cleanly with analog signal chains that use split rails. The 25uA per-amplifier disabled current allows system controllers to gate video channels dynamically in multi-camera or duty-cycled inspection equipment, conserving power in cabinet-level designs.
Recommended
Test and Measurement Signal Conditioning
Bench instruments, signal generators, and channel-multiplexed measurement front ends benefit from the EL5306's combination of 350MHz small-signal bandwidth and deterministic fixed gain of +1, -1, or +2. Because gain resistors are internal, gain accuracy does not drift with board assembly variation, which simplifies instrument calibration. The enable pin allows individual channels to be powered down to 25uA each in multi-channel instruments, and the wide 5V to 12V supply span accommodates the varied supply architectures found in modular test equipment and data acquisition front ends.
Recommended
Communication and Networking Video Ports
Networking equipment with local video diagnostics or management display outputs can use the EL5306 to buffer and drive RGB or composite video signals at 350MHz bandwidth. The single-supply 5V to 10V operating range matches typical networking board power rails, eliminating an extra regulator. Low differential gain and phase (0.02%, 0.04 degrees driving 150 ohm at gain 2) preserve image quality on status monitors, while the low 1.5mA per-amplifier draw keeps the always-on management plane's power budget small in high-port-count switches and routers with multiple local display outputs.

Design Notes
Operate the EL5306 within a supply span of at least 5V and less than 11V: 5V to 10V single-supply or ±2.5V to ±5V dual-supply, per the datasheet. Total quiescent draw is about 4.5mA (three amplifiers at 1.5mA each). If using the enable function for power saving, remember the disabled current is 25uA per amplifier, so a fully disabled EL5306 still draws roughly 75uA - account for this in battery-budget calculations rather than assuming zero shutdown current.
The CE (enable) pin is enabled when floating or driven low, per the datasheet - the opposite polarity of many amplifier shutdown pins. If your system requires a guaranteed disabled state at power-up, drive CE to the disabling logic level actively; do not rely on a pull-down or floating trace, which leaves the amplifier enabled. Decouple each supply pin with 0.1uF ceramics placed close to the package, standard practice for 350MHz amplifiers.
To preserve the datasheet's 0.02% dG and 0.04 degree dP video performance, use controlled-impedance (75 ohm or 150 ohm doubled-terminated) routing on all three signal channels with matched lengths to keep channel skew low. Because the gain-setting resistors are internal, do not add series resistance in the gain path; external resistance would alter the internal gain network's assumed load and degrade gain accuracy and bandwidth flatness.
