EL2250CS Equivalent & Substitute Parts

Part Overview

The EL2250CS is a dual-channel voltage feedback amplifier manufactured by Renesas Electronics Corporation, housed in an 8-SOIC surface mount package. This linear amplifier is designed for video amplification applications with a -3dB bandwidth of 125 MHz and slew rate of 275V/µs. The part is classified as obsolete, making equivalent and substitute components necessary for new designs and ongoing production requirements. Substitute parts must maintain compatibility with the 8-SOIC package format and support the voltage feedback amplification topology while meeting or exceeding the electrical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL2250CS 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 direct PCB footprint compatibility.

Circuit Configuration: The EL2250CS contains 2 circuits (dual-channel configuration). Substitute parts must maintain this dual-channel topology.

Amplifier Type: The EL2250CS is a voltage feedback amplifier. Substitute parts classified as voltage feedback amplifiers are primary candidates. Buffer amplifiers (MAX4203ESA+T, MAX4204ESA+) represent functional alternatives with enhanced performance characteristics but different amplification topologies.

Electrical Performance Envelope: Substitute parts must support the voltage supply range of 2.7V to 12V (single supply) or ±1.35V to 6V (dual supply). Output current capability must meet or exceed 100 mA per channel. Bandwidth and slew rate specifications in substitute parts may exceed the original specification.

Product Status and Compliance: Active status substitute parts are preferred for new designs. RoHS3 compliance is available in most substitute options, addressing environmental and regulatory requirements not met by the obsolete EL2250CS.

Engineering Selection Recommendations

For Direct Voltage Feedback Topology Replacement:

The AD8056ARZ-REEL, OPA2614ID, OPA2614IDR, OPA2652U, and OPA2652U/2K5 maintain the voltage feedback amplifier classification of the EL2250CS. Among these options, the OPA2652U and OPA2652U/2K5 (Texas Instruments SpeedPlus™ series) provide the closest performance envelope with -3dB bandwidth of 700 MHz and slew rate of 335V/µs, exceeding the original specification while maintaining output current capability of 140 mA per channel. Both OPA2652 variants are RoHS3 compliant and carry active product status.

The AD8056ARZ-REEL (Analog Devices) offers voltage feedback topology with 300 MHz bandwidth and 1400V/µs slew rate, with reduced output current of 60 mA per channel. This part is RoHS3 compliant and available in Tape & Reel packaging.

The OPA2614ID and OPA2614IDR (Texas Instruments) provide voltage feedback amplification with differential output configuration, 180 MHz bandwidth, and 350 mA output current per channel, supporting higher current applications. Both variants are RoHS3 compliant with active status.

For Enhanced Performance with Buffer Topology:

The MAX4203ESA+T and MAX4204ESA+ (Analog Devices/Maxim Integrated) represent buffer amplifier alternatives with significantly enhanced bandwidth (530 MHz and 720 MHz respectively) and slew rate (4200V/µs). These parts are RoHS3 compliant and active. The MAX4203ESA+T is available in Tape & Reel packaging, while MAX4204ESA+ is supplied in Tube packaging. Output current specifications are 90 mA and 52 mA per channel respectively, which may be limiting for applications requiring the full 100 mA per channel of the original part.

Compliance Consideration:

All substitute parts listed are RoHS3 compliant, addressing regulatory requirements. The EL2250CS is RoHS non-compliant; substitution enables compliance with current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the EL2250CS be directly replaced with any of the listed substitute parts?

A: Direct replacement requires matching the 8-SOIC package format, which all listed substitutes provide. However, functional compatibility depends on application requirements. Voltage feedback amplifiers (AD8056ARZ-REEL, OPA2614ID, OPA2614IDR, OPA2652U, OPA2652U/2K5) maintain the same amplification topology as the EL2250CS. Buffer amplifiers (MAX4203ESA+T, MAX4204ESA+) offer different topological characteristics and may require circuit design modifications.

Q: What is the primary difference between voltage feedback and buffer amplifier topologies?

A: Voltage feedback amplifiers sense output voltage to establish feedback control, suitable for precision amplification with moderate bandwidth. Buffer amplifiers provide high-speed signal buffering with minimal impedance transformation. The EL2250CS is a voltage feedback amplifier; buffer substitutes offer enhanced bandwidth but different operational characteristics.

Q: Are there supply voltage compatibility concerns when substituting the EL2250CS?

A: The EL2250CS supports 2.7V to 12V single supply or ±1.35V to 6V dual supply. Most substitute parts require minimum 5V to 8V supply voltage. Applications using the lower 2.7V to 5V range of the original part may not be compatible with AD8056ARZ-REEL, MAX4203ESA+T, or MAX4204ESA+. The OPA2614ID/OPA2614IDR and OPA2652U/OPA2652U/2K5 support 5V to 12V, accommodating most applications.

Q: What is the significance of RoHS3 compliance in substitute selection?

A: RoHS3 compliance indicates conformance to current environmental and hazardous substance restrictions. The EL2250CS is RoHS non-compliant. All listed substitute parts are RoHS3 compliant, enabling use in applications and markets requiring environmental compliance certification.

Q: How do output current specifications affect substitution suitability?

A: The EL2250CS provides 100 mA output current per channel. The AD8056ARZ-REEL (60 mA), MAX4203ESA+T (90 mA), and MAX4204ESA+ (52 mA) have reduced output current capability. Applications requiring the full 100 mA per channel should use OPA2614ID/OPA2614IDR (350 mA) or OPA2652U/OPA2652U/2K5 (140 mA).

Q: What packaging options are available for substitute parts?

A: Substitute parts are supplied in Tube, Tape & Reel (TR), or unspecified packaging. AD8056ARZ-REEL and OPA2614IDR are supplied in Tape & Reel format, suitable for automated assembly. MAX4204ESA+ and OPA2614ID are supplied in Tube packaging. OPA2652U and OPA2652U/2K5 are supplied in Tube and unspecified formats respectively. Packaging selection depends on production volume and assembly process requirements.

Q: Is the OPA2614IDR a suitable replacement for the OPA2614ID?

A: Yes. OPA2614IDR is the Tape & Reel variant of OPA2614ID with identical electrical specifications. Selection between them depends on packaging and assembly requirements. Both are RoHS3 compliant with active product status.

Q: How do bandwidth specifications compare across substitute options?

A: The EL2250CS provides 125 MHz bandwidth. Substitute options range from 180 MHz (OPA2614ID/OPA2614IDR) to 720 MHz (MAX4204ESA+). Higher bandwidth substitutes provide enhanced frequency response capability but may introduce increased noise in applications not requiring extended bandwidth. Selection should match application frequency requirements.
