MAX4461TESA Equivalent & Substitute Parts

Part Overview

The MAX4461TESA is an instrumentation amplifier manufactured by Analog Devices Inc./Maxim Integrated, designed for single-circuit rail-to-rail amplification applications. This device is classified as obsolete, which necessitates identification of active equivalent parts to ensure continued design support and procurement availability. The MAX4461TESA operates across a supply voltage range of 2.85 V to 5.25 V and is housed in an 8-SOIC surface mount package. Finding suitable substitutes is critical for new designs, production continuity, and long-term component sourcing strategies.

Substitute Part Grouping Explanation

Substitution of the MAX4461TESA is determined by strict equivalence across all electrical and mechanical parameters. The substitute relationship is based on the following criteria:

Electrical Parameter Equivalence:

• Amplifier type (Instrumentation)
• Number of circuits (1)
• Output type (Rail-to-Rail)
• Slew rate (0.5 V/µs)
• Gain bandwidth product (2.5 MHz)
• -3dB bandwidth (250 kHz)
• Input bias current (1 pA)
• Input offset voltage (50 µV)
• Supply current (800 µA)
• Output current per channel (150 mA)
• Supply voltage range (2.85 V to 5.25 V)
• Operating temperature range (-40°C to 85°C)

Mechanical & Packaging Equivalence:

• Package type (8-SOIC)
• Package dimensions (0.154", 3.90mm Width)
• Mounting type (Surface Mount)

Compliance & Regulatory Equivalence:

• RoHS3 compliance
• MSL rating (1 - Unlimited)
• REACH status (Unaffected)

The MAX4461TESA+ meets all these criteria and is therefore a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MAX4461TESA+ is the direct substitute for the obsolete MAX4461TESA. Both parts share identical electrical specifications, mechanical packaging, and regulatory compliance certifications. The primary distinction is product status: the MAX4461TESA is obsolete, while the MAX4461TESA+ is active and currently in production.

Selection Basis:

1. Electrical Compatibility: All electrical parameters are identical across both parts, ensuring drop-in replacement capability in existing circuit designs.

2. Mechanical Compatibility: Both parts use the 8-SOIC surface mount package with identical dimensions, allowing direct PCB layout reuse without modification.

3. Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited), satisfying environmental and reliability requirements.

4. Procurement Status: The MAX4461TESA+ is actively manufactured and stocked (1801 Pcs available), whereas the MAX4461TESA is obsolete with limited remaining inventory (988 Pcs). For new designs and production continuity, the MAX4461TESA+ is the appropriate selection.

5. Packaging Consideration: The MAX4461TESA+ is supplied in tube packaging, which is standard for active production parts and suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the MAX4461TESA+ be used as a direct replacement for the MAX4461TESA in existing designs?

A: Yes. The MAX4461TESA+ is electrically and mechanically identical to the MAX4461TESA. All electrical parameters, package dimensions, and pin configurations are equivalent. No circuit modifications or PCB redesign are required.

Q: What is the difference between MAX4461TESA and MAX4461TESA+?

A: The primary difference is product status and packaging. The MAX4461TESA is obsolete, while the MAX4461TESA+ is an active production part supplied in tube packaging. All electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry an MSL rating of 1 (Unlimited). Regulatory and environmental compliance is equivalent.

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

A: Both the MAX4461TESA and MAX4461TESA+ operate across a supply voltage range of 2.85 V to 5.25 V, supporting single or dual supply configurations within this range.

Q: What is the package type and mounting method?

A: Both parts are housed in an 8-SOIC surface mount package with dimensions of 0.154 inches (3.90 mm) width. This package is compatible with standard surface mount assembly equipment.

Q: What is the input bias current specification?

A: The input bias current for both parts is 1 pA (picoampere), indicating extremely low input current draw suitable for high-impedance signal sources.

Q: What is the maximum output current per channel?

A: Both parts can deliver 150 mA of output current per channel, supporting moderate load driving capability in instrumentation applications.

Q: Why should I select the MAX4461TESA+ over the MAX4461TESA?

A: The MAX4461TESA+ should be selected for new designs and production applications because it is an active production part with assured long-term availability. The MAX4461TESA is obsolete and subject to inventory depletion. Both parts are electrically and mechanically equivalent, making the MAX4461TESA+ the appropriate choice for design continuity and supply chain reliability.
