MAX4372TESA Current Sense Amplifier Equivalent & Substitute Parts

Part Overview

The MAX4372TESA is a current sense amplifier integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This linear amplifier device is designed for single-circuit current sensing applications and is packaged in an 8-SOIC surface mount configuration. The MAX4372TESA operates across a wide supply voltage range of 2.7 V to 28 V and maintains stable performance across industrial temperature ranges from -40°C to 85°C.

The MAX4372TESA is classified as an obsolete product. Locating equivalent or substitute components becomes necessary when original inventory is depleted or when design requirements mandate components with active product status and current manufacturing support. Identifying functionally compatible alternatives ensures design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4372TESA is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: Current Sense (single-circuit configuration)
• -3dB Bandwidth: 275 kHz
• Current - Input Bias: 2 µA
• Voltage - Input Offset: 300 µV
• Current - Supply: 30 µA
• Voltage - Supply Span: 2.7 V to 28 V
• Operating Temperature Range: -40°C to 85°C

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Supplier Device Package: 8-SOIC

All substitute parts must maintain identical electrical performance specifications and physical package dimensions to ensure direct functional replacement without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

MAX4372TESA+ as Primary Substitute:

The MAX4372TESA+ is the direct functional equivalent of the MAX4372TESA. Both devices share identical electrical specifications across all critical parameters including bandwidth, input bias current, input offset voltage, supply current, and operating temperature range. Both components utilize the same 8-SOIC package with identical physical dimensions, enabling direct pin-compatible replacement without PCB modification.

Compliance and Product Status Considerations:

The MAX4372TESA is classified as obsolete with RoHS non-compliant status. The MAX4372TESA+ maintains active product status with ROHS3 compliance certification. Selection of the MAX4372TESA+ provides access to current manufacturing support, documented supply chain availability, and compliance with modern environmental regulations. Both components carry identical REACH Unaffected and EAR99 ECCN classifications.

Packaging Distinction:

The MAX4372TESA+ is supplied in Tube packaging, whereas the original MAX4372TESA packaging specification is not provided. This packaging difference does not affect electrical or mechanical compatibility and represents a standard industry variation in component delivery format.

Frequently Asked Questions (FAQ)

Q: Can MAX4372TESA+ directly replace MAX4372TESA in existing designs?

A: Yes. The MAX4372TESA+ is electrically and mechanically equivalent to the MAX4372TESA. All electrical parameters including bandwidth, bias current, offset voltage, supply current, and operating temperature range are identical. The 8-SOIC package dimensions are identical, enabling direct pin-compatible substitution without circuit redesign or PCB layout modification.

Q: What is the primary difference between MAX4372TESA and MAX4372TESA+?

A: The primary differences are product status and regulatory compliance. The MAX4372TESA is obsolete and RoHS non-compliant. The MAX4372TESA+ is an active product with ROHS3 compliance certification. Both devices are functionally identical in electrical performance and physical package configuration.

Q: Are there any supply voltage or temperature range limitations when substituting MAX4372TESA+ for MAX4372TESA?

A: No. Both devices operate across identical supply voltage ranges (2.7 V to 28 V) and identical temperature ranges (-40°C to 85°C). No operational limitations exist when substituting the MAX4372TESA+ for the MAX4372TESA.

Q: Does the Tube packaging of MAX4372TESA+ affect compatibility?

A: No. Tube packaging is a delivery and handling format that does not affect the electrical or mechanical properties of the component itself. The device remains functionally identical and pin-compatible regardless of packaging format.

Q: What is the significance of ROHS3 compliance on MAX4372TESA+?

A: ROHS3 compliance indicates the MAX4372TESA+ meets current environmental regulations restricting hazardous substances in electrical and electronic equipment. This certification is relevant for applications subject to regulatory compliance requirements or customer specifications mandating RoHS-compliant components.

Q: Can MAX4372TESA be used in new designs?

A: The MAX4372TESA is classified as obsolete. For new designs, the MAX4372TESA+ is the recommended selection, as it provides active product status, current manufacturing support, and regulatory compliance certification.
