Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL2250CSZ is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts.

Dual-Channel Configuration: The EL2250CSZ contains two independent amplifier circuits. Substitute parts must maintain this dual-channel architecture.

Voltage Feedback Topology: The primary amplifier type is voltage feedback. Substitute parts classified as voltage feedback amplifiers are preferred for functional equivalence, though buffer amplifiers with compatible electrical characteristics are included.

Supply Voltage Range: The EL2250CSZ operates across 2.7V to 12V single supply or ±1.35V to ±6V dual supply. Substitute parts must support overlapping or compatible supply voltage ranges to function in existing circuit designs.

Bandwidth and Slew Rate: The -3dB bandwidth of 125 MHz and slew rate of 275V/µs define the frequency response and transient performance. Substitute parts with equal or superior bandwidth and slew rate characteristics maintain or improve upon the original performance envelope.

Output Current Capability: The 100 mA per channel output current requirement must be met or exceeded by substitute parts to ensure adequate drive capability for load impedances.

Compliance and Certification: All substitute parts must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory and environmental requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Voltage Feedback Amplifiers):

The OPA2652U and OPA2652U/2K5 from Texas Instruments are the preferred substitutes for the EL2250CSZ. Both devices maintain voltage feedback topology, dual-channel configuration, and 8-SOIC packaging. The OPA2652 series offers superior bandwidth (700 MHz) and slew rate (335V/µs) compared to the original part, with output current capability of 140 mA per channel, exceeding the 100 mA requirement. These parts are active products with ROHS3 compliance and MSL 2 rating, providing improved moisture handling compared to the original MSL 3 specification.

The OPA2614ID and OPA2614IDR from Texas Instruments are alternative voltage feedback substitutes with differential output configuration. These devices provide 180 MHz bandwidth and 145V/µs slew rate, with significantly higher output current capability of 350 mA per channel. The OPA2614 series supports supply voltages from 5V to 12V, compatible with the EL2250CSZ operating range. Both tube and tape-and-reel packaging options are available.

The AD8056ARZ-REEL from Analog Devices is a voltage feedback amplifier with 300 MHz bandwidth and 1400V/µs slew rate, substantially exceeding the original performance specifications. Output current is rated at 60 mA per channel, which is below the original 100 mA specification. This device is supplied in tape-and-reel packaging and maintains ROHS3 compliance with MSL 1 rating.

Secondary Substitute (Buffer Amplifier):

The MAX4204ESA+ from Analog Devices/Maxim Integrated is classified as a buffer amplifier rather than voltage feedback topology. This device offers exceptional bandwidth (720 MHz) and slew rate (4200V/µs), but output current is limited to 52 mA per channel, below the original specification. The MAX4204 is suitable only for applications where output current requirements are reduced or where buffer functionality is acceptable. This part is supplied in tube packaging with MSL 1 rating.

Supply Voltage Considerations:

The EL2250CSZ supports operation from 2.7V single supply. The AD8056ARZ-REEL, MAX4204ESA+, OPA2614ID, OPA2614IDR, OPA2652U, and OPA2652U/2K5 all require minimum supply voltages of 5V to 8V. Applications operating at supply voltages below 5V cannot use these substitutes without circuit redesign.

Product Status and Availability:

All substitute parts listed are active products with current manufacturing status, ensuring long-term availability and supply chain continuity. The EL2250CSZ is obsolete, making substitution necessary for new designs and ongoing production support.

Frequently Asked Questions (FAQ)

Q: Can the OPA2652U directly replace the EL2250CSZ in existing designs?

A: The OPA2652U is pin-compatible within the 8-SOIC package and maintains dual-channel voltage feedback topology. However, the minimum supply voltage requirement of 6V must be verified against the original circuit design. If the EL2250CSZ operates at supply voltages below 6V, circuit modification is required. The OPA2652U offers superior performance characteristics (700 MHz bandwidth, 335V/µs slew rate, 140 mA output current) and improved moisture sensitivity rating (MSL 1 versus MSL 3).

Q: What is the difference between the OPA2614ID and OPA2614IDR?

A: The OPA2614ID and OPA2614IDR are functionally identical voltage feedback amplifiers with identical electrical specifications. The primary difference is packaging format: OPA2614ID is supplied in tube packaging, while OPA2614IDR is supplied in tape-and-reel format. Both devices feature differential output configuration, 180 MHz bandwidth, and 350 mA per channel output current. Selection between these variants depends on production assembly requirements and component handling procedures.

Q: Why does the MAX4204ESA+ have lower output current than the EL2250CSZ?

A: The MAX4204ESA+ is classified as a buffer amplifier rather than a voltage feedback amplifier. Buffer amplifiers are optimized for high-speed signal transmission with minimal loading effects, resulting in lower output current capability (52 mA per channel) compared to the EL2250CSZ (100 mA per channel). The MAX4204 is suitable for applications where output current requirements are reduced or where buffer functionality is the primary requirement.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all substitute parts listed (AD8056ARZ-REEL, MAX4204ESA+, OPA2614ID, OPA2614IDR, OPA2652U, OPA2652U/2K5) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of the Moisture Sensitivity Level (MSL) rating?

A: The MSL rating indicates the maximum time a component can be exposed to ambient conditions (typically 30°C, 85% relative humidity) before soldering without risk of moisture-induced failure. The EL2250CSZ has MSL 3 (168 hours), while all substitute parts have MSL 1 or MSL 2 ratings. Lower MSL values indicate improved moisture tolerance and reduced risk of delamination or internal corrosion during storage and assembly processes.

Q: Can the OPA2614 series be used in applications requiring the full 100 mA output current of the EL2250CSZ?

A: Yes, the OPA2614ID and OPA2614IDR exceed the 100 mA per channel requirement with 350 mA output current capability. These devices are suitable for applications requiring high output current drive. However, the differential output configuration differs from the single-ended output of the EL2250CSZ, requiring circuit topology verification.

Q: What supply voltage range is compatible with all substitute parts?

A: The overlapping supply voltage range compatible with all substitute parts is 8V to 12V. Applications requiring operation below 8V must use only the OPA2614ID or OPA2614IDR (minimum 5V) or the OPA2652U/OPA2652U/2K5 (minimum 6V). The EL2250CSZ minimum supply voltage of 2.7V is not supported by any substitute part listed.

Q: Are there packaging considerations when substituting the EL2250CSZ?

A: All substitute parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package, ensuring mechanical compatibility with existing PCB layouts. Packaging format options differ: OPA2652U and MAX4204ESA+ are supplied in tube format, AD8056ARZ-REEL and OPA2614IDR are supplied in tape-and-reel format, and OPA2614ID is supplied in tube format. Selection depends on production assembly equipment and component handling procedures.
