ADA4528-2ARMZ-RL Equivalent & Substitute Parts

Part Overview

The ADA4528-2ARMZ-RL is an active linear operational amplifier manufactured by Analog Devices Inc., classified as a zero-drift amplifier with dual-channel configuration in an 8-MSOP surface mount package. This component is designed for precision analog signal conditioning applications requiring minimal input offset voltage and low input bias current. The device operates across a wide supply voltage range of 2.2 V to 5.5 V and maintains performance across the industrial temperature range of -40°C to 125°C. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when packaging format differences exist while maintaining identical electrical performance and mechanical compatibility within the specified package family.

Substitute Part Grouping Explanation

Substitute parts for the ADA4528-2ARMZ-RL are identified based on strict electrical and mechanical parameter equivalence. The substitution logic is governed by the following criteria:

Electrical Parameter Equivalence: All substitute parts must maintain identical specifications across the following parameters: amplifier type (zero-drift), number of circuits (2), output type (rail-to-rail), slew rate (0.5 V/µs), gain bandwidth product (3.4 MHz), -3dB bandwidth (6.5 MHz), input bias current (125 pA), input offset voltage (0.3 µV), supply current per channel (1.5 mA), output current per channel (40 mA), supply voltage range (2.2 V to 5.5 V), and operating temperature range (-40°C to 125°C).

Mechanical and Package Compatibility: All substitute parts must use the same base product number (ADA4528), the same package family (8-MSOP with 0.118" width, 3.00 mm), and surface mount mounting type. The package designation 8-TSSOP and 8-MSOP are mechanically and electrically interchangeable within this product line.

Compliance and Regulatory Status: All substitute parts must maintain identical RoHS3 compliance, moisture sensitivity level (MSL 1), REACH status (unaffected), and ECCN classification (EAR99).

Packaging Format Differentiation: The primary distinction between the main part and its substitute is the supply format. The ADA4528-2ARMZ-RL is supplied in Tape & Reel (TR) format, while the substitute ADA4528-2ARMZ-R7 is supplied in Cut Tape (CT) and Digi-Reel® format. Both formats contain identical die and lead frame configurations, differing only in the carrier medium and reel specification.

Parameter Comparison

Engineering Selection Recommendations

Selection between the ADA4528-2ARMZ-RL and ADA4528-2ARMZ-R7 is determined by procurement and assembly requirements rather than electrical performance or functional capability. Both parts are manufactured by Analog Devices Inc. and maintain active product status with full RoHS3 compliance and REACH unaffected designation.

The ADA4528-2ARMZ-RL in Tape & Reel format is suitable for high-volume automated assembly operations where continuous reel feeding is required. This format optimizes pick-and-place machine compatibility and reduces handling time in production environments.

The ADA4528-2ARMZ-R7 in Cut Tape and Digi-Reel® format is suitable for lower-volume production runs, prototype development, and applications where partial reel quantities are required. This format reduces material waste and storage requirements for components not immediately consumed in production.

Both parts carry identical electrical specifications, package dimensions, thermal characteristics, and regulatory compliance certifications. The choice between formats does not affect circuit performance, reliability, or long-term operational characteristics. Selection should be based on production volume, assembly equipment capability, and inventory management strategy.

Frequently Asked Questions (FAQ)

Q: Are the ADA4528-2ARMZ-RL and ADA4528-2ARMZ-R7 electrically identical?

A: Yes. Both parts contain identical die, lead frame configuration, and electrical specifications. All performance parameters including slew rate, gain bandwidth product, input offset voltage, and supply current are identical across both part numbers.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) format supplies components on a continuous reel suitable for automated high-speed assembly lines. Cut Tape (CT) and Digi-Reel® format supplies components in shorter tape segments or alternative reel configurations, suitable for lower-volume production and manual assembly operations. The physical component and electrical performance remain unchanged.

Q: Can I substitute the ADA4528-2ARMZ-R7 for the ADA4528-2ARMZ-RL in my design?

A: Yes, direct substitution is possible from an electrical and mechanical standpoint. The component will function identically in the circuit. Verify that your assembly equipment can accommodate the Cut Tape and Digi-Reel® format if switching from Tape & Reel supply.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ADA4528-2ARMZ-RL and ADA4528-2ARMZ-R7 are RoHS3 compliant with moisture sensitivity level 1 (unlimited) and REACH unaffected status.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the industrial temperature range of -40°C to 125°C with identical performance specifications maintained throughout this range.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts use the 8-MSOP package with identical pin configuration, lead spacing (0.118" width, 3.00 mm), and surface mount footprint. No PCB redesign is required when switching between these part numbers.

Q: What is the supply voltage range for these amplifiers?

A: Both parts operate with a supply voltage range of 2.2 V to 5.5 V, supporting single-supply and dual-supply configurations within this specification.

Q: Is there a difference in availability between the two part numbers?

A: Availability varies based on current inventory levels and production schedules. The ADA4528-2ARMZ-R7 typically maintains higher stock levels due to its suitability for diverse packaging requirements. Consult current inventory data for specific lead times and quantities.
