Product details
Overview
EL2250CSZ-T7 from Intersil is a dual-channel, single-supply voltage-feedback operational amplifier optimized for high-speed video and analog signal conditioning. It delivers 125MHz -3dB bandwidth, 275V/µs slew rate, and 0.05%/0.05° differential gain/phase at +5V supply, enabling distortion-free RGB, composite video, and A/D driver applications in portable and industrial systems.
For engineers reviewing the EL2250CSZ-T7 datasheet, EL2250CSZ-T7 pinout, EL2250CSZ-T7 application, or EL2250CSZ-T7 equivalent, key selection criteria include its rail-to-rail output swing to ground (no saturation), input common-mode range extending to GND and within 1.2V of VS+, ±100mA output drive, and guaranteed operation from +2.7V to +12V with industrial temperature support (-40°C to +85°C).
Technical Context
The EL2250CSZ-T7 uses a voltage-feedback architecture supporting reactive feedback networks for active filtering and stable gain configurations up to +10. Its input stage operates down to GND and up to VS−1.2V, while the output stage drives to GND without recovery delay and within 1.2V of VS+ under 1kΩ load.
It achieves 30MHz ±0.1dB flatness and 80dB open-loop gain, with low 4mV max offset voltage and 48nV/√Hz input noise-enabling precision DC-coupled video gain stages and high-fidelity line drivers where phase linearity and settling time (<40ns to 0.1%) are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5GHz GBW but lower output current (±75mA); requires dual supply for full input range. | Better for RF IF amplification; less suitable for single-supply video clamping or ground-swinging loads. | Choose LMH6629MA/NOPB only when >500MHz small-signal bandwidth is required and supply headroom permits split rails. |
| ADA4817-2ACPZ-R7 | Faster 1GHz GBW and lower 4nV/√Hz noise, but limited input range (to VS−1.4V) and no guaranteed ground-swing output. | Preferred for low-noise photodiode transimpedance or precision instrumentation; not validated for NTSC dG/dP compliance. | Choose ADA4817-2ACPZ-R7 for ultra-low-noise, high-GBW applications where video distortion specs are not mandatory. |
Compared with LMH6629MA/NOPB and ADA4817-2ACPZ-R7, the EL2250CSZ-T7 uniquely combines guaranteed rail-to-ground output swing, broadcast-grade video linearity, and industrial temperature operation in a cost-optimized SO-8 package-making it the preferred choice for volume video interface and portable analog signal chain designs.

FAQ
What supply voltage range does the EL2250CSZ-T7 support?
The EL2250CSZ-T7 operates from a total supply voltage of +2.7V to +12V on a single supply (GND to VS+), or ±1.35V to ±6V on dual supplies. Performance is optimized at +5V, where it achieves 125MHz bandwidth and 0.05% differential gain. The input common-mode range spans 0V to VS−1.2V, and the output swings to 0V without saturation-making EL2250CSZ-T7 ideal for low-voltage portable video systems.
Does the EL2250CSZ-T7 support true rail-to-rail output swing?
The EL2250CSZ-T7 drives its output to ground (0V) without saturation or recovery delay-a key differentiator for video sync-tip handling and DC-coupled applications. It also swings to within 1.2V of VS+ under 1kΩ load. While not rail-to-rail on the positive side, its ground-swing capability eliminates external pull-down resistors in most video clamping circuits, preserving EL2250CSZ-T7's specified 0.05° differential phase accuracy.
Can the EL2250CSZ-T7 be used in dual-amplifier configurations with independent gains?
Yes-the EL2250CSZ-T7 integrates two fully independent op amps in one SO-8 package, each with dedicated inputs (INA+/INA−, INB+/INB−) and outputs (OUTA, OUTB). Feedback networks can be configured separately for non-inverting, inverting, or differential gain-enabling matched RGB channel amplification or dual-path active filtering. Channel-to-channel isolation exceeds 60dB at 10MHz, ensuring minimal crosstalk in EL2250CSZ-T7-based systems.
What is the maximum load current the EL2250CSZ-T7 can drive reliably?
The EL2250CSZ-T7 delivers ±100mA peak output current into a 10Ω load at ±5V supply, and ±60mA into 50Ω. For continuous operation, Intersil recommends limiting output current to ±90mA to maintain junction temperature below 150°C. With proper PCB layout (ground plane, local 4.7µF + 0.1µF bypassing), EL2250CSZ-T7 sustains full performance driving 150Ω video loads or 50Ω transmission lines without external buffers.
Is the EL2250CSZ-T7 RoHS compliant and lead-free?
Yes-EL2250CSZ-T7 features Intersil's Pb-free plus anneal construction: 100% matte tin termination, RoHS-compliant molding compound and die attach, and MSL-3 rating per J-STD-020. It is compatible with both SnPb and Pb-free solder reflow profiles, and the "Z" suffix explicitly denotes the RoHS-compliant variant. This makes EL2250CSZ-T7 suitable for global industrial and consumer electronics manufacturing with full traceability.
