MAX412EPA+ Equivalent & Substitute Parts

Part Overview

The MAX412EPA+ is a general-purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, configured as a dual-circuit (2-channel) device in an 8-PDIP through-hole package. This part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The MAX412EPA+ operates across a supply voltage range of 4.8V to 10.5V with a slew rate of 4.5V/µs and gain-bandwidth product of 28 MHz, serving applications requiring general-purpose amplification in legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX412EPA+ is determined by the following critical parameters: dual-circuit configuration (2 channels), 8-DIP through-hole package format, compatible supply voltage ranges, and compliance certifications (ROHS3, REACH Unaffected, EAR99). The substitute parts identified—AD8056ANZ and AD8072JNZ—share the same physical package, pin count, and mounting technology, enabling direct socket replacement in existing PCB designs.

Key substitution criteria:

• Package compatibility: 8-DIP (0.300", 7.62mm)
• Dual-circuit architecture (2 amplifiers per package)
• Through-hole mounting
• RoHS3 compliance
• Operating temperature range overlap
• Supply voltage compatibility within specified ranges

The AD8056ANZ represents an active-status alternative with enhanced performance characteristics (higher slew rate and bandwidth), while the AD8072JNZ offers current-feedback topology optimized for video and high-speed applications. Both parts maintain electrical and mechanical compatibility with the MAX412EPA+ footprint and pinout.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement in legacy systems: The AD8056ANZ is the primary substitute for the MAX412EPA+ in applications requiring active-status component availability. Both parts maintain ROHS3 compliance, unlimited moisture sensitivity rating, and REACH unaffected status. The AD8056ANZ operates across an 8V to 12V supply range, which overlaps with the MAX412EPA+ specification (4.8V to 10.5V) in the 8V to 10.5V window. The extended operating temperature range of the AD8056ANZ (-40°C to 125°C) provides additional margin beyond the MAX412EPA+ specification (-40°C to 85°C).

For performance-enhanced applications: The AD8072JNZ offers current-feedback topology with 500V/µs slew rate and 100 MHz bandwidth, suitable for applications where the MAX412EPA+ general-purpose characteristics are insufficient. This part is classified as Last Time Buy, indicating limited future availability. The AD8072JNZ supports both single supply (5V to 12V) and dual supply (±2.5V to ±6V) configurations, providing flexibility beyond the MAX412EPA+ single-supply design.

Compliance and regulatory considerations: All three parts maintain identical RoHS3 compliance, MSL rating, REACH status, and ECCN/HTSUS classifications, ensuring regulatory equivalence for procurement and supply chain purposes.

Frequently Asked Questions (FAQ)

Q: Can the AD8056ANZ directly replace the MAX412EPA+ in existing PCB designs? A: Yes. Both parts use identical 8-DIP through-hole packaging with the same physical dimensions (0.300", 7.62mm) and pin configuration. No PCB modifications are required for socket replacement.

Q: What are the supply voltage compatibility considerations? A: The MAX412EPA+ operates from 4.8V to 10.5V. The AD8056ANZ operates from 8V to 12V. Direct substitution is valid when the system supply voltage falls within the overlapping range of 8V to 10.5V. For systems operating below 8V, the AD8056ANZ is not suitable.

Q: How do the performance characteristics differ between these parts? A: The AD8056ANZ provides significantly higher slew rate (1400V/µs vs. 4.5V/µs) and bandwidth (300 MHz vs. 28 MHz GBW), making it suitable for higher-frequency applications. The AD8072JNZ uses current-feedback topology optimized for video and transient response, with 500V/µs slew rate and 100 MHz bandwidth.

Q: What is the significance of the product status classifications? A: MAX412EPA+ is obsolete, indicating no further manufacturing or support. AD8056ANZ is active, ensuring continued availability and support. AD8072JNZ is Last Time Buy, indicating a final production run with limited future availability.

Q: Are there input bias current differences that affect circuit design? A: The MAX412EPA+ specifies 80 nA input bias current, while the AD8056ANZ specifies 400 nA. For applications sensitive to input bias current (high-impedance sources, precision instrumentation), this 5× difference may require circuit compensation adjustments.

Q: Do all three parts meet the same regulatory and compliance standards? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, classified as EAR99, and carry identical HTSUS codes (8542.33.0001). Moisture sensitivity level is 1 (unlimited) for all parts.

Q: What is the operating temperature range consideration for substitution? A: The MAX412EPA+ operates from -40°C to 85°C. The AD8056ANZ extends this to -40°C to 125°C, providing additional thermal margin. The AD8072JNZ temperature range is not specified in the provided data. For applications operating near the upper temperature limit, the AD8056ANZ offers improved headroom.
