MAX412EPA Equivalent & Substitute Parts Reference

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 component is classified as obsolete, which necessitates identification of functionally equivalent substitute parts for ongoing design requirements and production continuity. 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, making it suitable for general-purpose amplification applications requiring moderate bandwidth performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX412EPA are selected based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Mechanical Compatibility:

• Package type: 8-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Number of circuits: 2 (dual-channel configuration)

Electrical Compatibility Criteria:

• Supply voltage range overlap with original specification (4.8V to 10.5V minimum requirement)
• Output current capability per channel (minimum 35 mA)
• Input bias current and offset voltage characteristics suitable for general-purpose applications
• Operating temperature range coverage (-40°C minimum)

The identified substitute parts (AD8056ANZ and AD8072JNZ) maintain identical package and pinout compatibility while offering enhanced electrical performance characteristics. Both substitutes are manufactured by Analog Devices Inc., ensuring design continuity and supply chain reliability.

Engineering Selection Recommendations

AD8056ANZ Selection Criteria:

The AD8056ANZ is classified as an active product with extended production support. This substitute provides superior electrical performance with a slew rate of 1400V/µs and -3dB bandwidth of 300 MHz, representing a significant performance enhancement over the MAX412EPA. The AD8056ANZ operates within a supply voltage range of 8V to 12V, which overlaps the upper portion of the MAX412EPA specification (4.8V to 10.5V). Applications requiring operation below 8V supply voltage cannot use this substitute. The AD8056ANZ supports an extended operating temperature range of -40°C to 125°C, exceeding the MAX412EPA specification. Output current capability is 60 mA per channel, exceeding the 35 mA requirement. ROHS3 compliance and MSL-1 rating are maintained.

AD8072JNZ Selection Criteria:

The AD8072JNZ is designated as Last Time Buy, indicating limited future availability. This substitute employs current feedback topology, differing from the general-purpose architecture of the MAX412EPA. The AD8072JNZ provides a slew rate of 500V/µs and -3dB bandwidth of 100 MHz. Supply voltage operation is specified as ±2.5V to ±6V (dual supply) or 5V to 12V (single supply), with the single-supply range overlapping the MAX412EPA specification. Output current per channel is 30 mA, which is below the 35 mA requirement of the MAX412EPA. ROHS3 compliance and MSL-1 rating are maintained.

Recommendation Logic:

For applications requiring immediate substitution with active product status and extended supply voltage flexibility, AD8056ANZ is the primary selection. For applications with specific current feedback topology requirements or constrained to Last Time Buy inventory, AD8072JNZ is applicable with verification that 30 mA output current meets circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the AD8056ANZ be used in applications requiring supply voltages below 8V?

A: No. The AD8056ANZ minimum supply voltage specification is 8V. The MAX412EPA operates from 4.8V minimum. Applications requiring operation below 8V cannot use the AD8056ANZ as a direct substitute.

Q: What is the primary difference between the AD8056ANZ and AD8072JNZ topologies?

A: The AD8056ANZ employs voltage feedback architecture, while the AD8072JNZ uses current feedback topology. These represent different amplifier design approaches with distinct frequency response and stability characteristics. Topology selection depends on specific application requirements.

Q: Is the AD8072JNZ output current of 30 mA sufficient to replace the MAX412EPA 35 mA specification?

A: The AD8072JNZ output current per channel is 30 mA, which is below the MAX412EPA specification of 35 mA. Substitution is valid only if the application circuit requires less than 30 mA output current per channel.

Q: Are all three parts (MAX412EPA, AD8056ANZ, AD8072JNZ) pin-compatible?

A: Yes. All three parts are configured in 8-DIP (0.300", 7.62mm) through-hole packages with identical pinout, enabling direct socket substitution without PCB modification.

Q: What is the significance of the AD8072JNZ "Last Time Buy" status?

A: Last Time Buy designation indicates that Analog Devices Inc. has announced end-of-life for this product. Future availability is limited to existing inventory. New designs should not incorporate this part; existing designs using this part should plan transition to alternative solutions.

Q: Does the extended operating temperature range of AD8056ANZ (-40°C to 125°C) provide additional design margin?

A: Yes. The AD8056ANZ supports operation to 125°C, compared to the MAX412EPA maximum of 85°C. This provides additional thermal margin for applications operating in elevated temperature environments.

Q: Are RoHS and REACH compliance maintained across all substitute parts?

A: Yes. All three parts (MAX412EPA, AD8056ANZ, AD8072JNZ) maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compliance continuity.
