ADA4077-1ARZ-RL Equivalent & Substitute Parts

Part Overview

The ADA4077-1ARZ-RL is a general-purpose operational amplifier manufactured by Analog Devices Inc., designed for linear amplification applications. This single-circuit, 8-SOIC surface-mount device operates across a wide supply voltage range of 5V to 30V and maintains active product status with full RoHS3 compliance. Substitute parts are identified when original inventory becomes unavailable, when supply chain constraints occur, or when design flexibility permits alternative amplifier topologies that meet application requirements within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitute parts for the ADA4077-1ARZ-RL are identified based on strict compatibility criteria within the linear amplifier category. The primary substitution logic is based on the following allowed parameters:

Package Compatibility: Both the main part and substitute must use the 8-SOIC surface-mount package with identical physical dimensions (0.154", 3.90mm Width) to ensure direct PCB footprint compatibility without layout redesign.

Supply Voltage Range: Substitute parts must operate within or encompass the minimum 5V to maximum 30V supply voltage specification of the ADA4077-1ARZ-RL. Parts with narrower supply ranges may be acceptable if the application operates within their specified limits.

Single Circuit Configuration: Substitute parts must contain exactly one amplifier circuit to match the single-circuit topology of the main part.

Surface Mount Technology: Both parts must use surface-mount mounting technology for compatibility with automated assembly processes.

Compliance Standards: Substitute parts must maintain RoHS3 compliance and REACH unaffected status to satisfy regulatory and environmental requirements equivalent to the main part.

Operating Temperature Range: Substitute parts must support the application's operating temperature requirements. The ADA4077-1ARZ-RL operates from -40°C to 125°C; substitute parts operating within this range or a subset thereof are acceptable depending on application needs.

The INA141UA meets these substitution criteria through identical package specifications, compatible supply voltage range, single-circuit configuration, surface-mount technology, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The ADA4077-1ARZ-RL remains the preferred component when original specifications are required. Both the main part and the INA141UA substitute maintain active product status and full RoHS3 compliance, ensuring regulatory compliance and long-term availability support.

Substitution Applicability:

The INA141UA functions as a direct mechanical substitute due to identical 8-SOIC package specifications and surface-mount compatibility. Both devices operate within overlapping supply voltage ranges (4.5V to 36V for INA141UA encompasses the 5V to 30V requirement of ADA4077-1ARZ-RL). Both maintain single-circuit configurations and equivalent compliance certifications.

Functional Differences:

The INA141UA is classified as an instrumentation amplifier, whereas the ADA4077-1ARZ-RL is a general-purpose amplifier. This functional distinction affects circuit behavior and application suitability. The INA141UA exhibits higher slew rate (4V/µs versus 1.2V/µs), lower input bias current (2 pA versus 400 pA), and lower output current capability (15 mA versus 22 mA). The INA141UA operates to a maximum temperature of 85°C, compared to 125°C for the ADA4077-1ARZ-RL.

Compliance and Regulatory Status:

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying equivalent environmental and regulatory requirements. Both are classified under identical HTSUS code 8542.33.0001 and ECCN EAR99.

Selection Decision:

Component selection between ADA4077-1ARZ-RL and INA141UA depends on application-specific requirements for amplifier topology, temperature range, slew rate, and output current. Mechanical and electrical compatibility exists within the specified parameter ranges; however, functional differences require application-level evaluation.

Frequently Asked Questions (FAQ)

Q: Can the INA141UA replace the ADA4077-1ARZ-RL in any application?

A: The INA141UA provides mechanical compatibility through identical 8-SOIC packaging and surface-mount technology. Electrical compatibility exists within specified supply voltage ranges (4.5V to 36V for INA141UA covers the 5V to 30V requirement). However, functional differences between instrumentation and general-purpose amplifier topologies require application-specific evaluation. The INA141UA operates to 85°C maximum temperature, whereas the ADA4077-1ARZ-RL operates to 125°C.

Q: Are there package compatibility concerns between these parts?

A: No. Both the ADA4077-1ARZ-RL and INA141UA use identical 8-SOIC packages with 0.154" width and 3.90mm dimensions. Both employ surface-mount technology. Direct PCB footprint compatibility exists without layout modification.

Q: What are the key electrical differences between these amplifiers?

A: The ADA4077-1ARZ-RL provides higher output current (22 mA versus 15 mA) and operates to higher maximum temperature (125°C versus 85°C). The INA141UA provides higher slew rate (4V/µs versus 1.2V/µs) and significantly lower input bias current (2 pA versus 400 pA). Supply current consumption is higher for the INA141UA (750µA versus 400µA).

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the ADA4077-1ARZ-RL and INA141UA maintain RoHS3 compliance and REACH unaffected status. Both are classified under ECCN EAR99 and HTSUS code 8542.33.0001. Both maintain active product status.

Q: What is the difference between a general-purpose amplifier and an instrumentation amplifier?

A: General-purpose amplifiers like the ADA4077-1ARZ-RL provide basic amplification functionality with flexible gain and configuration options. Instrumentation amplifiers like the INA141UA are optimized for precision measurement applications with integrated input stage design, typically offering lower input bias current and higher common-mode rejection. The INA141UA is specifically designed for low-power, precision applications.

Q: Can I use the INA141UA if my application requires operation above 85°C?

A: No. The INA141UA maximum operating temperature is 85°C. Applications requiring operation to 125°C must use the ADA4077-1ARZ-RL or identify alternative parts with equivalent temperature ratings.

Q: Are there supply voltage considerations when substituting these parts?

A: The INA141UA supply voltage range (4.5V to 36V) encompasses the ADA4077-1ARZ-RL range (5V to 30V). If your application operates at exactly 4.5V, the INA141UA is compatible while the ADA4077-1ARZ-RL is not. Both parts operate across the full 5V to 30V range.
