ADA4004-2ARMZ-RL Equivalent & Substitute Parts

Part Overview

The ADA4004-2ARMZ-RL is a general purpose operational amplifier manufactured by Analog Devices Inc., featuring dual circuits in an 8-MSOP surface mount package. This device is classified as an iPolar® series amplifier with active product status and full RoHS3 compliance. The ADA4004-2ARMZ-RL is suitable for applications requiring low input bias current and low input offset voltage in a compact form factor. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, design flexibility, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADA4004-2ARMZ-RL is determined by compatibility across the following critical parameters: dual-circuit general purpose amplifier configuration, surface mount technology with 8-pin package footprint, supply voltage range of 10V to 30V, output current capability of 10mA per channel, and RoHS3 compliance. The substitute parts identified are Texas Instruments RC4558 series devices, which maintain the same package footprint and electrical supply specifications. However, substitution introduces trade-offs in performance characteristics. The RC4558 series exhibits lower slew rate (1.7V/µs versus 2.7V/µs), reduced gain bandwidth product (3MHz versus 12MHz), higher input bias current (150nA versus 40nA), and higher input offset voltage (500µV versus 40µV). Operating temperature ranges differ between the main part and certain substitutes. These performance differences must be evaluated against application requirements before substitution is implemented.

Parameter Comparison

Engineering Selection Recommendations

RC4558IDGKR is the primary substitute for the ADA4004-2ARMZ-RL. This device maintains active product status, operates across an extended temperature range of -40°C to 85°C, and carries full RoHS3 compliance. The RC4558IDGKR is available in high inventory (37,750 pieces) and is supplied in Cut Tape and Digi-Reel® packaging. While this substitute exhibits reduced slew rate, gain bandwidth product, and higher input bias and offset voltages compared to the ADA4004-2ARMZ-RL, it maintains compatibility with the 8-pin surface mount package footprint and supply voltage specifications.

RC4558DGKR is a secondary substitute option with active product status and Tape & Reel packaging. This device operates within a narrower temperature range (0°C to 70°C) and exhibits identical electrical performance characteristics to the RC4558IDGKR. Selection of this part is appropriate only for applications with operating temperature requirements within 0°C to 70°C.

RC4558DGKRG4 is not recommended for new designs. Although this device shares electrical specifications with other RC4558 variants, it carries obsolete product status and is supplied in Cut Tape and Digi-Reel® packaging. Continued use of obsolete components introduces supply chain risk and limits long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the RC4558IDGKR directly replace the ADA4004-2ARMZ-RL in existing designs?

A: The RC4558IDGKR is mechanically compatible with the ADA4004-2ARMZ-RL, sharing the same 8-pin surface mount package footprint and supply voltage range. However, electrical performance differs significantly. The RC4558IDGKR exhibits lower slew rate (1.7V/µs versus 2.7V/µs), reduced gain bandwidth product (3MHz versus 12MHz), higher input bias current (150nA versus 40nA), and higher input offset voltage (500µV versus 40µV). Applications sensitive to these parameters require circuit redesign or performance verification before substitution.

Q: What is the difference between RC4558DGKR and RC4558IDGKR?

A: Both devices share identical electrical specifications and package footprint. The primary difference is operating temperature range. The RC4558DGKR operates from 0°C to 70°C, while the RC4558IDGKR operates from -40°C to 85°C. The RC4558IDGKR is suitable for applications requiring extended temperature operation. Packaging differs: RC4558DGKR is supplied in Tape & Reel, while RC4558IDGKR is supplied in Cut Tape and Digi-Reel®.

Q: Why is RC4558DGKRG4 not recommended?

A: The RC4558DGKRG4 carries obsolete product status. Use of obsolete components introduces supply chain risk, limits future availability, and may complicate long-term product support. Active alternatives such as RC4558IDGKR are preferred for new designs and ongoing production.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The ADA4004-2ARMZ-RL and all identified substitute parts (RC4558DGKR, RC4558DGKRG4, RC4558IDGKR) carry ROHS3 compliance certification. All devices also maintain Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected status.

Q: What packaging options are available for substitute parts?

A: RC4558DGKR is supplied in Tape & Reel (TR) packaging. RC4558DGKRG4 and RC4558IDGKR are supplied in Cut Tape (CT) and Digi-Reel® packaging. The ADA4004-2ARMZ-RL is supplied in Tape & Reel (TR). Packaging selection depends on production volume and assembly process requirements.

Q: How do supply voltages compare between the main part and substitutes?

A: All devices operate within identical supply voltage specifications: minimum 10V and maximum 30V. This parameter is fully compatible across all parts, eliminating power supply redesign requirements.
